Got like 1 mpg boost which was good considering I have a level kit and 10 ply all terrain tires. This product complements my Volent cold air intake. Anywhere from 18mpg to 21 mpg that all depends on my driving too. Felt a little better throttle response as well!

I already have a cat back system, k&n intake, and tuner on my 18 Silverado and this spacer made a big low end difference. I notice an improvement on take off and throttle response immediately. I do not notice anything on the top end but that may be different on a stock truck. I tow a lot of weight and it made a huge difference in take off with an attached trailer. It was worth the money for me and I will probably try them on my other vehicles. I do not know what it does for fuel mileage, I do not track my mileage.

Easy install and cleaned out my throttle body while in there. My mileage went up 1.5 mpg. No noticeable noise difference. 14 Chevy w/5.3. Everything was there in box and was solidly built.

Easy installation dyno showed 1/2 the horsepower and torque advertised

Great product! Installed it on my 2014 silverado in less then 20 min. Noticed a difference in the torque on acceleration. Woke my truck right up.

Love it! Felt the difference right off the bat, the air flow was super smooth! ESP on the take off and combined with my AFE intake I couldn’t be more pleased.

I got it and it was awesome
