Thanks for confirming that , I would rather keep my engine clean , I have been reading and your not the only one that said this I will stay away, I will get the tried and true K&N filters with the pre filters

Did you do install yourself? It seems pretty straight forward was there any modifying to be done to make it fit ? Thanks
