K&N 63 Series AirCharger High-Flow Intake Kit Reviews

K&N 63 Series AirCharger High-Flow Intake.

Reviewed By Jack S (Kearney, MO) Reviewed for a 2011 GMC Sierra —2/11/2016 8:16 AM

Noticed quick throttle response right away. Had to modify the L shaped mounting bracket for the air box.The front bolt that holds the top on the air box needs to be tweaked, you can't get screwdriver on it because of the finder well. I put the bolt in from the inside and put a wing nut on the outside, worked great. Very satisfied with product. I don't know about mileage increase I haven't driven it enough to tell.

Great product. Exact as described. Great price, extremely friendly support and quick shipment. Definite notice in throttle response and power. Down shifts less on hills, and recovers quicker when it does. Looks great under the hood. Highly recommended!!!

Reviewed By Girard H (RENO, NV) Reviewed for a 2014 GMC Sierra —12/6/2015 5:50 PM

This kit took me about 90 minutes to install from the gathering of my tools to cleaning up and taking it for a spin. The instructions were very precise and all parts were of high quality to ease in the installation process. I've noticed more power on the low end and most of all the aggressive, race-inspired growl coming from under the hood is one to let you know the engine is performing more to its potential. Great product and company to order from. I highly recommend.
