I have a Place Racing CAI on my 98 Maxima. I want to change the monsterflow to a K&N air filter. What part number K&N would it be to fit on my PR CAI? Ive heard K&N RU-2820 and 1 other one I cant remember. Which part number is it? And which should I get, cone or stack? I've checked the http://maxmods.dyndns.org/?MaximaIntakes website but I couldnt find it. Thanks for the help, but not for the flames I'm undoubtedly gonna get.

 

I used K&N RR-3001 which is shorter then RU-2820 but has a inverted design, I love it. BTW, I have Injen and it has a 3" intake

 

Bump, still looking for K&N filter part # for my Place Racing CAI.
