Sinister Diesel Cold Air Intake 11-12 Chevy / GMC Duramax 6.6L LMLQ: I know it is stronger and looks better, but doesn't aluminum conduct more heat than plastic? A: On a technical standpoint, aluminum would be a little more subject the heat because it is metal, but, it is thin walled tubing, and would also dissipate the heat much faster as air is moving. The issue with a plastic intake, while it takes just as much time to heat up, it takes a considerable amount more time to dissipate that heat build up, also known

Bonded to services well, completely removed panel reverberation in my tacoma. Also really made the doors so much quieter even when closing. Very happy with the result. Used only one set on my 01 tacoma 4 door. Installed inside doors on exterior skin panel, over interior door panel access holes (sealing the door to provide backpressure to door speakers (left drains open)), roof panel, and back wall of cab. Achieved about 70% coverage and am very happy. 2 8in SKAR SVR8 at 1oh on walmart power acustic 2500 (only rated to ~800rms at 2oh, forum showed testing at 1oh worked about 1kw) in 6th order with blow through into cab. With cab gain, im over 130db between ~30 and ~50hz. This was a necessary addition!
