Talking K&n

Hello everyone,
I was wondering if anyone has a K&N air filter in there RX-8??? I was wondering if there would b better gas mileage then a oem mazda filter........ I'm not really looking for more horsepower but better gas mileage and cost saving when replacing the filter.

Thanx

I'd say the main cost saver is not having to buy new air filters after the K&N.. and tons of us have one in.

The only intake that seemed to give better fuel economy was Racing Beat and maybe 5hp. A lot of members have said they got 3-5 extra mpg, albeit you don't have a lead foot. Not so sure about the K&N intake.

i think that was more of a placebo effect when they first came out..

i have had the racing beat intake and duct on for ~ 65k miles. mpg is the same.

only increase in mpg would be from replacing a really dirty one with a clean one.

Oh, in that case, there is no hope of an intake that increases mpg. lol

Thanx for the replys.......... If a K&N will give me the same gas milage as a stock air filter I'm cool with that.... I just like the fact that the K&N is re-usable

k&n didn't improve my mpg, but it makes my throttle slightly more responsive.
