Review on 🚀 High Performance K&N Cold Air Intake Kit: Guaranteed Horsepower Increase - Fits 1999-2007 Chevy/GMC/Cadillac (Silverado 1500/2500, Suburban, Tahoe, Sierra 1500/2500, Yukon, Escalade) V8, 77-3023KP by Danny Flores

Received 4/8/2020 all in good condition. Instructions are good, could do with some improvement but for over $300 you would expect quality screws. They require a square head, no problem BUT round our DO completely tight. Assembly delayed by CHEAP screws. Now we need to go to the local source. May or may not revise my review. I'm sure one star is unfair but I'm P###ED! (You fill in the blanks). I'm sure it will improve my car's pulling power once installed, but these ### cheap props are unforgivable for a high-end company like K&N.5/18/21. UPDATE: After I calmed down, I upped my rating to a three. Stars b/c it improved MPG by 15% from 8.5mpg to 10mpg in RV towing. But inferior screws reduce my rating from 5 to 3.
