My Friend has been telling me to get a intake for the reason of increased fuel economy? Is this true? Does it make a difference?
Thanks,
Doug

Not true. If the factory air intake is very restictive you may gain a few horsepower from swithching it out to a system with less restriction. Mileage gains would be imperceptable. Driving like a granny will yield better results in the MPG department.

if you drive the same with and without an intake, you may see some gain in mileage...it depends on the vehicle also...i drive a 2002 offbrand, and my mileage increased when i changed my intake, exhaust and thermostat...

Offbrander! You should be banished from thee land! :D

Id get a ram intake if I were you... simply because if you run through a big puddle, your going to slurp up water. Also any aftermarket will give you little horsepower, but you will notice a difference in power, and your car will sound throatier and better. Here is a pic of my 00' Civic with a short ram intake.

But is the Mileage gained worth the money places in getting a Intake? When would the investment pay for itself?

In this car, It ain't no Muscle Car.

1991 Accord Kinda Banged up.

Doug

you can get them VERY cheap on ebay, and if you dont have a "nice" car...just buy a cheap one...i bought an ebay intake for my car and did some work and its just as good as anything K&N or AEM makes...for 250 dollars less for my application.

There isnt a miles worth of difference than the ebay and the $200 intakes. Though, on bigger engines it will give you better gas mileage... they are more effective on V8'

I thought that they do give you better milage if you drive normal but if you start flooring it then your mpg will go down.

I've had CAI's and short Ram's on the past three (and current) cars. I've yet to see an actual MPG increase. Not arguing, just stating what I have seen in use. On the other hand I haven not noticed any decrease unless your right foot stays in it!

well, my foot never gets out of any of my vehicles, including my beatera..so i wouldnt know about that..[8D]

I know that they make your engine run more effecient so in theory it could give you better mpg. And if you get cai then go with one with a bypass valve for when it is wet. My friend blew an 05 civic with only like 1000 miles on it because he got the engine all wet. He had to get it all rebuilt. Actually his girl was driving his car. I guess he shuodla told her.

Thats what happens when women drive a car lol! A man can take a truck and go through trees, mud and tear off in rocks, but when his girlfriend drives down a road at the speed limit, it will blow up. That was just a funny saying (not that I hate women... I love em!) btw.

You and me both!!

i heard all of the "hydrolock" stories..and for a while..i wouldnt take my car out in the rain...if i got caught in the rain, i would just disconnect my MAFS from the lower portion of the CAI...and get home ASAP...but after 2 years of not driving in the rain, or stopping to mess with my CAI..i thought, hell with it..i have a warranty...and now i dont bother..and ive been in some pretty HARD rain..and never had a problem...to hydrolock an engine, you basically have to drive into a DEPP puddle...just driving in the rain wont do it...

yeah it was a puddle. Man was he pissed. I don't think they had a warranty because it is still sitting in his front yard waiting for the engine to be rebuilt. It was also lowered so maybe that is a dangerous combination.

when things happen liek that..people far too often take the car into the dealership for warranty work with the aftermarket piece on the car. there was a law passd a few years ago that states, for a warranty to be voided by an aftermarket performance part, the warranty company must prove beyond any doubt that the aftermarket piece was the DIRECT CAUSE of the issue. i have seen guys drop a 200dry shot onto a stock motor, fry the motor, and take it back to the dealership with the bottle pulled out, and have the engine repair FOC....:)

"200dry shot onto a stock motor"

Can i ask what this is?

Speaking of Gas mileage.
I'm truly a novice at modifing cars, shoot I just installed my first set of Ignition wires on the 1991 accord and my mpg shot up from 23.5 to 26.04mpg. I was impressed by the change, going to flip out the rotor and cap this weekend.

Thanks,
Doug

Please do not shout!! We can see the ordinary size print just fine, thank you.

200 dry shot into a stock motor..means..

200 dry shot is a measure of nitrous injection...200 means it is a 200hp gain, and dry shot means that there is no fuel added with the nitrous gas upon injection...and into a stock motor, means that there are no internal modifications done to the vehicle, thus it is unable to handle the amount of nitrous injected into the engine.

Ok Thanks for the explainatio to the Novice!

Doug

i thought that an induction kit and exhaust only really show power gains when you have the car chipped afterwards

No, that is wrong. Imagine trying to suck in air from a coffee straw... now imagine sucking air through a Mcdonalds straw. I rest my case.

lol thats a good example

The more efficiently your engine inhales and exhales air the better your power figures. IE Turbo, exhaust, intakes, headers, etc. They all aid in moving air through the engine as fast as possible. chipping changes how you engines controls it combustion and sometimes alters the max rpm, there are other factors too, but those are the basics.

aha, i see

i put a cold air intake on everything...

Like ive said b4 ive had all 3 aem intakes ( SR CAI and now V2) CAI was one of my favs but im soo in love with the V2's sound even though in the upper rpm its louder than my greddy evo2 exhaust

Also, of course you've heard the colder the intake charge (the air) the more power is yielded inside the combustion chamber. Hence the reason for nitrous shot into the intercooler or the cryogenic intake charge system.

Hot thread Gentlemen: I think I will start with teh AEM V2 Right away, as a reward for doing the belts, FuZion HRi's are in the mail - is there any greater anticipation than waiting for parts? Essencially it sounds like headers, exhaust intake is nice, but really all that work is prep for the installation of a turbo - True? If I were to look at a turbo down the line is there any ENGINE mods I'd need to make outside of what is listed above?

From another "true novice" A: what are the ignition wires, rotor and cap?
B: What does changing them out do for me? (you sparked my interest)

A header would have to to be removed for turbo and a turbo manifold would be installed in it's place. Mods are intended for the goal of the engine. Such as an exhaust for turbo is different than an exhaust for an N/A car. An intake would also be removed and a different intake would be needed for the turbo.

EDIT: Also, builing an engine is often suggested. Please view the link in the "GOOD TURBO INFO" thread for more on building engines. $$$$$$

Thing sin your ignition system get old and need replaced because they are not as efficient as they used to be ignition wires are the wires that connect the spark plugs to the distrutor cap. The cap has a rotor in it which sends the spark through the wires to the plugs and therefore causes combustion. Changing them is maintenance more than modification. Wires can go from $30-90 depending ont he wires and what type of ignition and engine they're for.

I noticed a positive change when I replaced my ignition leads and spark plugs, however my cars mileage was high and had stock leads and plugs.

some companies claim thier leads and plugs can free up a little BHP, but i dont really believe it-

They replacing things like they do nothing but restore lost hp. If you added new oem plugs you'd feel the same results.

If you plan on turboing defiantly dont waste money on headers an intake is a bit cheaper and id spend the money on one now even if i planned to turbo Another good mod is a grounding kit it doesnt add any horsepower but it frees up existing HP thats been lost over the years do to normal wear and tear on the electronics of the car.

Some grounding kits, w/ voltage regulators are better a little better. A'pexi had the best dyno number in a test conducted by one of the magazines. Can't remeber which one. Hondas generally have good stock grounding, but it'll help anyway. Don't start looking for 10hp though. Plus you'll get better results from a grounding kit w/ a turbo...since you won't have to remove it.

i see the cold air intakes on ebay. are they worth the money and will they make any kind of difference? or would they basically be a waste of money?

They're not a waste...the only difference between ebay and AEM or Injen is that they actually had R&D for the applications and some are DOT approved. Other than that they're all just a damn pipe that flows better than what the factory put on there...and sounds sweeter too. You may get a 1hp difference between intakes..if any at all.

I thought that they do give you better milage if you drive normal but if you start flooring it then your mpg will go down.


thats because the air intakes are designed to maximize airflow in ur intake manifold. if u run the piss outa your car, the gas MPG goes down... because the ECU has to balance out the fuel/air ratio. if your gettin more air.. you need more fuel to balance it out.. or else your cars gona not function properly

Good answer.

if i havent stated before, i have an "ebay intake" on my car...and with a K&N filter hooked to it instead of the cheap paper filter, it is every bit as good as the AEM unit, which costs 175-200 bucks more. [:'(]

I would tend to disagree depending on what type of change you did to the intake.
If you have it set up in any type of ram air or more freeflowing the car will see the increase and adapt to it to keep it from going lean so it will increase the gas flow to match it. You see more power but probably less gas mileage. Changing the temp of the air while keeping the flow the same may increase the gas mileage.
If all your after is better gas mileage changing to synthetic oil in both engine and trans, and cold air intake (maybe) and a better exaust system is about what you want to do. There are other ways also like different type tires.

I bought a full CAI off ebay seems to be great as far as ga mileage i dunno if it increased or helped but if u want better fuel economy running like supreme rather then regular will help you get more mileage you pay a little more but u get bettere mileage

The gains between the two aren't worth the price difference, unless your squeezing for hp that hard and have the funds to dish out. Be proud.

The filter is more important than a pipe.

A CAI inst much more money then a ram intake though id go with teh full CAI it actaulyl does give u more hp then the ram i tried the two i borrowed my buddys ram and then i bought my CAI and i noticed a dif...

i just went with the comptech ice box intake, it's one of the more pricier items on the marketm but
it looks stock, is deisgned to fit perfectly in my vehicle, at 3500 to 4000 rpm i can feel the intake drawing the air in from below the engine bay, and as a bonus, it actually has a nice deep tone at that rpm range.
of course below 3500rpm, no effect, thats vtec for you!!!

im not an engineer, but i do spend a helluva amount of time driving every day, hence, im pretty in tune with how the car car is perfoming. this mod has made a mild difference, when vtec changes over
at 3500, i now have better acceleration and i can feel the power gains thru the 6500rpm when i have the car if third, i have the manual tranny, 4th gear or D in my car is no fun!!!


gas mileage of course has suffered, however this is what i wanted, higer performance means economy be damned in my book!!!!

lets see what soem headers a high flow cat and nice cat back sytem will bring

everyone in here that thinks an aftermarket intake (ram or cold air) gives you better gas mileage is a complete idiot. more air means more fuel used, which means LOWER gas mileage!

way to pull up a 2 year old thread. to change the amount of fuel used, you would need to tune the car and tweak the ECU's fuel/air ratio. this cannot be changed any other way. what gives you more power isnt the increase of fuel of course, its the ease of moving the air. youre increasing efficiency. if you have ever lost mpg, it is most likely due to an inferior air filter.

It increases the mpg from better flow, better tuning, and its lighter than the oem intake. The only way you lose mpg is what Velocifero (http://www.hondaaccordforum.com/showProfile.asp?memid=6381)saidandbc you want to hear the throaty sound all the time.

if u want performance get that new AEM dryflow filter... altho its less quiet then the reg AEM filter it does make the engine/car run alot smoother

Nice 2 year jump in posts!!!

the Apexi filter is better than that.

Hey Nate...probably by mistake I'd say..[sm=bounceybounce.gif]

I must add this to this forum post for all to read...I bought my CAI to go faster as most of you have done, not to gain in fuel savings...I like to get my foot into the gas pedal and hear that Great sound that we get from them.
I also like the idea that itwasa Fast and Cheap way for me to get another approx 10 horsepower out of my V6...and by the way...it was great to go back a couple of years and see what we were talking about then: seems to be the same thing that we still talk about today in the 2007 forums :D

200 dollers
for 1-2 mpg

:D
you guys make me laugh.

intake=sound/looks
no so much performance.
if you want better gas mileage, dont rev over 3000 and you should be fine. biggest differernce is how you press the accelerator.

nate ..... while you are laughing at others, realize that the intake is free in about 2 years if 1.5 mpg is achieved.

12,000 mi per yr / 20 mpg = 600 gallons used per year

1.5/20 = 0.075 0.075*600 gal = 45 gallons saved per year

45 gallons per year * $2.50 per gal = $112.50 per year saved on gas


Note that gas is more expensive than $2.50 per gallon, so the payback period is actually less than 2 years ...... how long do you own cars before you sell them?

Yeah within 2 years MAX, it'll have paid for itself...

klr: That's assuming that you can control yourself enough to get better MPG with it on ...... I rev the hell out of my J30! 7k every day!!!

Actually since i've gotten my cat back installed, I've been riding it really hard...

I can't help it, i love the sound, and the performance boost... Yet I'm somehow still managing to get just about the same MPG (at this point, it's still spot on at 31mpg).

I'm surprised to say the least, but hey, i can't complain!

Now when I get my CAI installed this weekend, we'll see how that goes....

When I behave I can get about 22-23 MPG
