Easy install. Gave my Sierra a nice throaty grawl to it while punching it. Helped with HP as well.

This is a great add on to your truck or suv ! Sure does give it that V8 sound ! The install was very easy . It took about 40 mins . Wasn't in a rush but most people could get it done in 25 -30 mins . Just make sure you follow the instructions . They are on point and doesn't leave any steps out . Over all I give it a thumbs up . You can't go wrong with K&n . Also the price on this unit with Auto Anythings promo code and free shipping you won't find this cheaper ! Order it now .

I was able to easily install this myself with the enclosed instructions. I've noticed a small whistle sound if I really put my foot into it but most of the time it doesn't make a sound. I purchased a kit that included a cold air scoop and we couldn't figure out how to install that even with the instructions it included. That part remains to be installed and even without it, I've noticed increased performance.
