Review shared from K&N Series 63 AirCharger Cold Air Intake (19-25 5.3L Silverado 1500)
Not sure what i was expecting
But I bought it at my local advanced auto cause I didn't want to wait..took maybe an hour to hook up which I'm still not sure if it's seated right(not sure where that stupid rubber grommet sits)but whatever..this along with my awe exhaust makes it sound wicked! I'm in love..pretty sure I went through half a tank of gas in half hour from just hitting the throttle to listen to it lol

Works well but dry filters are better
Works well and I haven’t had any issues but it’s an oiled filter. I ordered a dry one from another brand. Makes cleaning much easier and cheaper. Those oil kits are like $20 and the process is just more tedious than necessary.

K&N 77 CAI
Excellent quality! Affordably purchased through open box. All components were in box. Makes the truck sound better and run better. I got an addition 1mpg (depending on driving but overall is 1mpg +\-)
