Do your self a favor and when you go to reoil/clean that K&N toss it in the trash instead and by a good Dry flow air filter from AEM, HKS or even stock.

The K&N are notorious for not only allowing too much debris into the engine... Also there is probably a 80% chance when you reoil it that its going to destroy your AFM.
