Review on Spectre Performance Air Intake Kit: High Performance Upgrade, Engineered to Boost Horsepower: Compatible with 1999-2007 CHEVROLET/GMC/CADILLAC (Silverado, Avalanche, Suburban, Tahoe, Sierra, Yukon, Escalade) SPE-9900 by Patrick Biletnikoff

Chevy 2002 2500hd Silverado 4x4 Extended Cab. As with any part of performance, maybe you're just driving on the freeway and when you get home you're checking for air leaks with the engine running. and tighten the clamps if necessary. I also replaced the mass air flow sensor since it was already disassembled. Good guide, removing old system and installing everything took about 45 minutes and I'm just a shade tree mechanic. After my 45-mile test ride, I tested it out of turn and throttle response seemed to improve. It has a nice deep, raspy sound, but not loud, and is almost inaudible on the freeway at 70mph. Can't comment on fuel economy or durability but I travel a lot so will update if anything happens. I recommend it for all of the reasons above.
