Well my MAF adapter from BAT came today so I pulled out the 3530 and went to put it on. I did a search to see if anyone has had issues with the flange diameter. Many said they thought it wouldn't work but didn't hear about anything after. When that clamp gets tightened the rubber flange will push out in one spot or another. This is with me holding the filter all the way on and someone else tightening the clamp. I finally used some pipe insulation, which was to thick to wrap all the way around the MAF adapter so I only used it on one half. Got worried that there would be small hole where the insulation ended and the MAF adapter started when done tightening it. What gives with it, anyone else had/having issues with theirs? Sucks to have 2 people put this thing on right. Might have to go to the 3130!
