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!
