K&n Airfilter - BMW Forum

Is K&N airfilter worth $45.
Do I really get any performance out of this filter compared to OEM.
I would appreciate if any of you have any personal experience with K&N.

Thanks

K

You get a little more air with the K&N which is good. You never have to buy another OEM filter, which is great.

A lot of conjecture on this subject on the E32 board with bottom line being very little if any improvement as the car has a near pefect built in cold air induction system.

You will save money in the long run and have more consistent performance. Theoretically you could clean that thing as often as you want and always have max airflow. There is no down side and you will save money, that said I see no reason not to.

I'd just get a whole new intake from EBAY

Well i sure like it. And I say save your money and make your own CAI. My brother helped me make mine (excluding the filter, that was boughten), and it works just as well as any other kit that costs a few hundred bucks.

OK! Today I replaced my OEM with K and N and i'm pleased so far.
I used to have slight rough idle and that is gone and can not tell if the engine is on or off unless i look at the rpm odometer.
reponse time has improved slightly too.
I think I'm sold on K and N filter.

Thanks for all your inputs.
