Exactly the performance I was looking for! Looking forward to hopefully get a few miles more per gallon as well. Looks great.

5 Star Review

I recently purchased a performance intake for my 08' Silverado 2500HD 6.0L. I was expecting a boost in HP and acceleration, but I wasn't expecting the sound it now makes. It completely changed the sound of my truck. It sounds awesome! I don't have dual exhaust but it literally makes it sound like I do. An opened up rumble sound is the best way I can describe it. I am very pleased with the new intake system.

5 Star Review

K&N, another solid, well thought out product. The increase in power and it sounds great. Instantly noticable without being obtrusive. Especially if you toss a Lower temp thermostat in , the reduced engine temperature is worth it in and of itself.
