Cold Air Intake vs. K&N drop in filter...Pros/Cons
 

i've got a 1987 porsche 944 n/a 2.5L. i've heard so many of my car-guy pals go on and on about this. thought i'd post it in a forum with people who actually have experience with them in their own porsche 944 (or other porsche). cold air intake vs. k&n drop-in filter (with factory airbox)???? worth the money? any gains? thought i'd ask before i spend the money.
thanks guys!!! ferdinand
