Jason,

I installed it as per instructions I put PTFE on the o-ring and connecting the filter to the engine it seized that hard that a screw driver and hammer was needed being billet aluminum it didn't like it too much. I was able to re thread it again the canister spins off but left the filter element and connecting piece still on the vehicle both off the threads are a right hand type. I spoke to K&N they were very helpful and resolved the matter immediately. Hopefully I don't have this prob with the second one. The dirt it collected plus the magnets that were visibly able to see was impressive. I still would like to know the microns it filters down too.
