Cone Filter Intake

has anyone that replaced their stock box with a K&N type cone intake seen a difference in gas mileage? I did a search on this but didnt really find anything regarding fuel economy improvements.

It is really not meant for fuel economy.

More for better airflow for more power.

Remember, always upgrade your muffler before you upgrade the intake.

I could use more HIGH END power. Low end is fine. I would probably benefit more from a wire/plug/cap/rotor replacement instead.

Always update the muffler first. It is the weak link in the performance chain. THEN, add an intake. The engine is a glorified air pump and if it cannot get rid of the air it uses, it can't intake as much air either.

And yes, a tuneup is always a smart thing to do.
