I have a 1997 E36 328i. I would like to increase performance, but am confused. Could someone please explain the basics of forced induction in relation to -

K&N Induction kits, cone filters and replacement air filter elements. Are they the same thing or do i need all three ? if not which is best and do they mean an insurance declaration ? what gains may I expect ?

Thanks in advance for any advice you may offer.

Forced induction refers to a devise that mechanically forced air into the engine. We're talking supercharging here. There are belt driven superchargers and turbine/exhaust driven superchargers called turbochargers. I prefer turbos for their performance benefits others will choose belt drives. Both are good and reliable but have different personalities.
I do like K+N filters and have used them for 20 years in all my vehicles and logged many miles with no ill effects. I do not use them for any performance gain but for the convenience of being able to clean it as frequently as needed instead buying a new paper filter. After a few cleanings they pay for themselves. They gains that are advertised, 15-20 Hp increase, hold true IF your engine already makes around 800Hp.

Thanks John, for the book recommendation. I am undecided about supercharging (rob-ace's fave) and turbo (Sweeney MA 86 635Turbo's choice). I'll look up that book. I have read Turbo mag...good info.
