Hey everyone i got a noobie air filter question, my friend used to have an s2k and he advised me to take the top of my air filter box so i would get a louder sound but how till i should replace the air filter or is there any out there that would create a similiar affect without having to expose it
and also how much do they cost???

 

I think the word "long" is missing in there somewhere...

If you want the nice sound, go with a CAI along the lines of the AEM, 4IGS, or Injen. The filter should probably be replaced every 10-15k miles stock, or reoil at that interval if using an AEM-style intake. Expect about a $150-$250 price tag for the mentioned CAIs.

I suggest against taking the stock box top off...while it may sound cool, you tend to lose several ponies, especially in hot weather.

 

...and also makes the filter dirty quicker.

 

also will cause heat soak
