Gas Mileage with Stillen CAI

Gas Mileage with Stillen CAI
anyone experienced reduced gas mileage after installing Stillen coldair intake in G35 coupe?
With the stock intake, i was getting around 350 miles/tank. After putting on the Stillen CAI, im getting like 300 miles/tank. Anyone knows why? Intake is the only mod i have in my car
Thinking of going back to stock but i dont have stock intake anymore cause the dealer installed my Stillen intake and i forgot to ask for my stock intake back.

Many have stated their MPG has gone up after installing an aftermarket intake.
Im guessing you have a typo on your MPG amounts. 350 MPG

I didn't change my driving habits. I tried to drive very moderately and still only could get 300 mpg/tank with the Stillen CAI. I think it's the Stillen.

I was getting a consistent 350 mpg/tank until i installed the Stillen CAI.

Either way, it can't be the stillen. Something else has changed your MPG; its either your driving, or something in the engine compartment itself.

eminem, have you changed your driving routes/habits at all? perhaps more street (stop/go) driving?

I think its theoretically impossible for an intake to worsen anyones MPG if its installed properly. An intake might lean out the AFR mixture; it's going to add more air to the mixture rather than fuel.
It's all behind the driving.

no guys i haven't changed my driving habits... i intentionally tried to drive very moderately like i did before i installed the stillen intake (mostly on freeway at around 75 mph) just to find out how many miles i could get after i installed the stillen intake... and i have been getting around 300 miles/tank
i guess i can check the tire pressure

Driving habits haven't changed.......?
You may not think your driving habit haven't changed, but they did the
minute you installed the Stillen CAI. Your subconscious is listening to the
sweet sound the intake is making and your right foot is reacting if you
know it or not! This works the same way when you install an exhaust
system. Customers complain that their gas mileage has gone down hill but
it's their right foot causing the problem.....most don't believe it but this is
the truth! We react to the sweet sounds are cars make, and I'm guilty too!
You may try disconnecting the battery for an hour and then reconnect but it
really won't make any difference......Happy Driving.
