Luckily I had one stock oil filter left. I've had the Ready filter and cover waiting on my bench until I used up my extra filters in stock. When I installed the Ready filter it was loose and did not appear to fit correctly. I did not feel it would filter the oil properly. Thank God I had a stock filter hiding on my bench since the one I pulled out now was lost in my trash can. I hope I can find the receipt , they ain't cheap. Any one try the Scott filter? Is it any better?
