I ordered the upr big mouth filter and maf adapter plate. I put on the filter and the screws litteraly fell off. They came right out of the rubber where they are housed. Went to my local speed shop and replaced it with a k&n and adapter plate and its perfect. I called upr to ask them if the filter was preoiled and they said yes, It wasn't. Never had a problem with upr before so this pissed me off. Had to vent
