hey quick question. I recently bought some Reddy Racing Pre-Oiled racing filters for my blaster. When i screwed the air filter in place on the housing, the screw goes right through the hole in the top of the filter and doesnt bring the filter with it, leaving the hole in the top open. Is this a problem? Should I just put a washer on it to hold the filter down? Also, what kind of grease should I get to get the filter to stick to the bottom of the filter housing? Thanks for the help
