I just installed my Frankencar midpie with a Stillen filter. THe clamp that holds the filter and the MAss Air sensor to the midpipe keep coming loose and the whole piece separates. Could this be a bad clamp. Or could it be because the filter is pushed up again some wire loom and part of the car. I just can't figure out what is wrong????

 

Geta friend and open the hood. Tell your friend to shift the car slowly between reverse and drive while on the brake so the car doesn't go anywhere. This will cause the engine to rotate slightly fore and aft in the engine bay. While he's doing that, look closely to see if the filter or midpipe is bumping up against something like the strut mount or battery causing it to wiggle its way loose.

Just a thought.

 

If I remember correctly, that piece was tighter than hell. Are you using a 3" rubber hose with two clamps between the midpipr and sensor? I know it is a stupid question, but ya never know.....
