K&N is king! I love my intake! The added performance is undeniable. It not only makes my 03 Sierra run great, but it sounds great too. The installation wasnt as easy at it was made to seem though. The rubber sleeve that connects the throttle body and the intake was very short, causing the clamps to keep slipping off when I tried tightening them to secure the intake to the throttle body. And if you have a TBSpacer like i do, you have to cut some of your fan guard to make it fit. All worth it tho!

Delivered immediately. Putting it on took me two days of exhausting work. The large hose will not bend and made of hard plastic. I had the hardest time aligning the hose so there would not be an air leak in the system. The book on how to install it needs some refining - it was not as advertised. How do you get the light for "check the engine" came on immediately - how do I shut it off without having to go to a dealership and loosing my warranty.

When I purchase it it came in his also I would like to see the holes to the intake was a little short and I had to take another option to hook up. Just let's hope it don't come off on me while on the freeway
