I did the air silencer removal mod, now if i were to get a drop in k&n filter will i notice any gains? Like better mpg, sound in intake, throttle response? I also have an exhaust (40 series f-master)......

 

I highly recommend the new Amsoil air filter over the K&N. It requires no oiling and filters better. All you do is blow it out or vacuum it clean and reuse. I removed the silencer and cut holes in my air box and could definitely hear throttle noise (very nice growl). I noticed a definite increase in git-up-n-go after replacing a basic air filter with the Amsoil about 2 months ago.

 

where can i get the amsoil filter at? Any auto parts store?

 

I believe you have to get it from a dealer. Bob is the man to contact. Great to work with and a really nice guy. His name on here is Soundperformance.

 

i noticed a small diference with the k&n and a cut up box

 

how much of a gain for mpg

 

i couldnt tell you. i didnt have it dynoed before and after
