Review on Airaid Cold Air Intake System AIR-200-796: Boosted Horsepower & Advanced Filtration | Compatible with 2007-2014 CADILLAC/CHEVROLET/GMC (Escalade, Suburban, Avalanche, Silverado, Tahoe, Yukon, Sierra) by Bobby Watkins

Purchased Airaid 200-796 Jr. for Suburb 2013. Sounds great, but none of these things add a real performance boost. The initial installation was easy. I would give 5 stars if the included coupler (first photo) between the stock airbox and the Airaid intake pipe was a bit longer. It was only 2 inches wide and after a little movement it slid off either the intake pipe or the airbox. I ended up buying a 3x3 flexible coupler (second photo) from Lowes' plumbing department. [.] Fits perfectly, looks as good or even better and doesn't slip off. Same quality filter as K&N.
