Anyone with the Comptech/CT Engineering intake knows that it can rub and vibrate under high engine load. It's very noticeable if you're at lower RPM and open the throttle up.

This had been bugging me for a while, so I finally decided to fix it.


Problem: airbox lid contacts hood prop-rod holder
Cause: notch cut in lid improperly sized; airbox does not sit perfectly against fender.
Solution: increase size of notch

Details: Basically I took my Dremel tool, put a small aluminum oxide grinding bit on it (the dark brown one) and slowly increased the size of the notch. The trick is to use low-speed and take it at a slow pace. Go too fast and you risk splintering/cracking the carbon fibre. I only made the notch about 1/4" bigger towards the windshield. Problem solved.



Problem: airbox plastic directly contacts passenger strut tower
Cause: airbox improperly sized; no barrier between metal strut tower and plastic airbox.
Solution: insert thick neoprene/rubber to dampen vibrations

Details: The back left corner of the airbox itself sits against the passenger strut tower. I'm not 100% certain this causes vibration, but plastic-to-metal certainly isn't desirable. I went to the hardware store, bought the thickest piece of neoprene I could find, cut a 2x2 square, and attached it to the airbox with double-sided tape. This provides a barrier between the airbox and the strut tower; neoprene squishes pretty well, so it doesn't adversely affect airbox fitment.



Problem: airbox lid directly contacts airbox
Cause: adhesive used on foam gaskets melts from engine temperatures
Solution: remove old foam, replace, use stronger adhesive

Solution: Comptech uses this really cheesy low-density foam with a weak adhesive. Over time, the adhesive melts and the foam slides around, ultimately falling off. Again, I went to the hardware store and bought some narrow high-density foam rubberstripping. I suggest getting very narrow stuff or you'll waste a lot of time trimming. Remove the old adhesive and foam with Goo Gone and some sandpaper to make sure you have a clean surface. Cut the weather stripping appropriately, and apply it.




There's no vibrations or resonances anymore. Again, I'm really disappointed in Comptech's engineering of this part. All their other items seem to be a step up from a lot of aftermarket parts, but they really dropped the ball on this. Fitment is absolutely horrible. Fortunately, it's easily corrected.
