K&N Cold Air Intake System: High-Flow Air Filter, Increase Performance & Towing: Compatible with 2016-2019 Chervolet/GMC: Silverado 2500 & 3500, Sierra 2500 & 3500, 77-3090KTK

Update: K&N is sending me a replacement intake tube! Nice work K&N. Really appreciate it!Original review:Excellent quality of parts except one little thing...the logo on intake tube was misplaced. Install was easy, took me just under an hour, instructions were very well done, step by step and easy to follow. 2018 silverado 2500HD 6.0 15K miles, The results: Before installing did a round trip test of milage. 6 miles in town and 56 miles freeway with cruise set at 74mph running Chevron 92 unleaded which resulted in 13.2mpg just normal driving. After install, and (after a 10 mile test drive) same exact trip resulted in 14.4mpg. 1.2mpg better and I even jumped on it a couple time. The sound is normal from closed at about half throttle then you start to hear it. At WOT it produced a mean growl! Dyno sheet supplied says a gain of 7hp and 8foot more torque (ish)...honestly its hard to tell or feel but It sounds more like 100hp! I like it and recomend.

Cold air intake filter system is absolutely amazing. Not interested in racing my vehicle but the power truck. I have no interest in racing my vehicle, but have noticed a performance increase. It does let people know that you have something under the hood but it’s not obvious until you accelerate it’s not like a muffler replacement that upsets the neighbors recommended 100%.

It's has definitely helped on my truck pulling my camper. Haven't really noticed a change in my fuel. Works great.

Did not get all of what was ordered. Contacted manufacturer and they also did not send what was needed. Returned product to Amazon for refund and will order elsewhere

When making performance mods to any vehicle you wouldn't expect to get any better fuel economy but this simple mod does. The changes aren't going to be outrageous, 2 mpg better and maybe 7 HP and a throatier sound when accelerating, but they are better. All of this combined equates to less stress on the engine as well. I notice lower oil temps at highway speeds which proves my last mention.Thanks again to K&N for a great product.

I have had these on my last 3 Chevy Trucks - the latest being a 2500 HD. They work well. Don't expect GREAT savings on Gas or power. You get "better" power and a little better fuel mileage. This is what I expected and what I got.

Just got done. Can't wait to stomp on it.

Received part late. Parts missing. Poor instructions. Called K&N and they hung up on me. The missing parts were clamps that where not in the parts bag. Dissatisfied , don't know if it was amazon or K&N.
