Sorry Woody,Woody said:Hey Troy,
Do you still have the sport exhaust or did you take it off & sell it already? I may be interested if you still have it. ??
A K&N filter is a brand of engine air filter. There are 2 types. I am assuming Iceburg is speaking of the "drop in" type that replaces the OEM one. The other is what I have which is a "cone" type in which you remove the whole stock air filter box & plum the filter right off the air flow meter-with this type you get a lot of increased noise. The K & N brand filters are cleanable & reusable (lifetime).
I don't pretend to know the "how". I simply noticed a change in noise.Rick480 said:How could a air filter possibly make a difference in the sound an engine makes?
I don't have any direct experience with the drop-in type.Rick480 said:How could a air filter possibly make a difference in the sound an engine makes? You could take the filter out all together and I doubt you could notice any humanly perceptable difference in performance or sound. The K&N filter certainly had no big effects on mine.
if you got the drop in filter that we did the instruction are for the 3 series, the X3 is much easermguhler said:Are the instructions that come with it ample? Or are there other instructions needed?
