Just got a PR CAI but it came with MonsterFlow air filter. Definately don't want to have a foam filter and want to get a K&N. I'm going to harass place racing to get them to send me a K&N filter instead of Monster Flow, no need to waste $60 for their mistake if I don't have too. If that plan falls through, which K&N filter should I use? There are hundreds out there, just want the part numbers so I can place an order.

Thanks in advance.
