11k + miles on mine w/no problems at all! Installed K&Ns @ 1k. Working very well for me. Don't over soak the filter when you clean it. Just enough oil to make it turn light red..... Not dark red..... Instructiuons are very clear. Been using them for years on virtuately everything I own with an engine w/no problems at all.

Again.... mine stay! :lol: :roll: :lol:
