Review on 🚀 K&N Cold Air Intake Kit: High Performance, Guaranteed to Increase Horsepower for 1999-2007 Chevy/GMC 4.3L V6 (Silverado 1500, Silverado 1500 Classic, Sierra 1500) - 50-State Legal - Model 57-3038 by Bob Novitsky

A mechanic friend of mine told me that this is the cheapest upgrade for the best performance for my truck. My truck no longer stops when driving uphill or accelerates to high revs. Sounds better and throttle response is better. It's too early to talk about fuel economy. It was easy to install, took about two hours and I was mostly looking for my tools. There is no step in the instructions. The front right throttle body bolt has a bracket for the linkage. There is a nut under this bracket that must be removed to align the coupler with the other two. I would recommend this to everyone. I'm buying one for my dad for Christmas.
