When to replace an AEM CAI air filter?

[rrcelica]

Hi, I have an AEM CAI and I was wondering how often should I replace the air filter, where can I get them and which brand is best?

Thanks,

Never, the K&N filter that came with it has a 1 MILLION mile warranty, all you have to do is by the recharger cleaning kit and clean it every 30-40 thousand miles, (the box says 50,000).

K&N is the best so far, but you just clean them when yours gets dirty. just check it, if you have a paper filter you might want to switch to a rechargable unit like K&N.
