Went to change my air filter the other day and got the K&N number off it and nobody can seem to find it in thier book. Went to 4 differant places. Does anyone have a replacement filter brand and number that will fit the paxton setup? Thanks.

Just measure the inlet size , then go on K&N web page. They will have a few to choose from. I got the largest one for my Procharger. More CFM,s and it takes longer before it gets dirty.

I ran whatever fit then always removed it at the track as even K&N's rob substantial HP.

Aren't you worried about sand? Do you have proof of the K&N's robbing a good amount of HP.

Even on a 264hp mild magnum (mine) the KN filter was holding back a solid 10hp on the dyno. (so I guess its really 254 :-p )

Centrifugal compressors can get away with unfiltered air occasionally for a short while, don't try it with a roots or twin screw.
