Review on 🚀 K&N Cold Air Intake Kit for 2007-2010 Chevy/GMC Heavy Duty (Silverado 2500/3500, Sierra 2500/3500) 6.6L V8 Diesel, 57-3066 – High Performance, Increased Horsepower, 50-State Legal by Brian Quenzer

K&N sells scrap on this air intake. It's very difficult to access a top cover screw (some reviewers just missed it). To remove and reinsert the filter, the inlet pipe must be unscrewed. It is very difficult to fix the inlet pipe with the filter in the box and the filter will not snap into place when the inlet pipe is fully installed. The airbox is made of very thin steel and will likely heat up the intake air. Whoever designed this should go back to school and shame K&N for selling it. I'm getting this junk back!
