| Re: k&n vs conventional price I`ve tried different filters.
ACDelco $20 oem filter: worked excellent. no loss in power. Engine could breathe easily.
Fram (cheap) made the engine behave differently and transmission also got a different shift algorithm. I also noticed a loss in power.
K&N $50 filter: Noticeable positive difference from Fram. Works great. I think that I have a little more peak power than with the ACDelco filter. Haven`t seen any difference in mpg.
In retrospect, I would choose the ACdelco filter and not worry about dirt, cleaning and oiling the K&N filter.
Hope this helps.
