the intake matches stock dimensions -.- no harm no foul. just extra noise. premium wont hurt, slight increase in mpg, and help ur engine run a little bit more efficent if ur having problems u havnt fixed yet.
*im at 200-250 a tank on reg, back at 300-320 with premium.
*exhaust smells like running rich, but no codes being thrown. might replace before/after cat just for ****s and giggles. o2 sensors

O2's will get "lazy" and cause a drop in MPG without setting codes. I hate to suggest throwing parts at an issue but you've ruled out most everything else....no leaks, up to date on tune up stuff, ect....

Pitted and leaky fuel lines would allow engine to run fine but appear to consume lots of gas. Check fuel pressure and if it won't hold, look for leaks or inspect for leaks.
Also if injectors have been moved, make sure the injector/fuel rail oring is sealing/not leaking.
good luck

I am sorry for the miss understanding in my previous post concerning Premium fuel. I didn't mean that it would cause a drop in fuel consumption.
I was under the assumption that the concern was use of excessive fuel which equates to excess in cost.. and the goal is to save money.. so my intension of saying "do not use premium" was to save money... it was not meant to mean an increase or decrease fuel consumption.
However, premium fuels to have more detergents than regular and the detergents tend to clean the injectors better, so using premium can at times benifit you that way.
I would suggest running injector cleaner from time to time just to keep the injectors clean instead of using premium gas.

Thanks for the info. I didn't know all grades of fuel now have the same cleaning agents... no more wasting money on injector cleaner
(but it seems, when I take a trip down to the beach and put injector cleaner in the tank, it seems like I get 20% better fuel economy, maybe it's just the excitement of going to the beach! )
