Your cart is empty.Throttle Body Spacer is designed to enhance off-idle torque from 800 rpm to approximately 3,000 rpm. The spacer utilizes it's unique, patented Helix Bore design to spin the incoming air charge as it passes through the throttle body spacer. The spinning air action boosts the velocity of the incoming air and contributes to better atomization of the air/fuel mixture as the air charge enters the combustion chamber. The end result is more part-throttle torque and improved mid-range power.

I had my truck tuned before with just a cold air intake and I shouldn’t have maybe would’ve worked with stock tune but was issues doing it after sounded great and could feel a little more dig off the line then normal

I haven't noticed anything. It doesn't make any noise like others have said. They probably installed it backwards. The instructions don't specify but it's common sense. I'm getting a cold air intake next week maybe that will help this thing out. Or just a waste of money. 2012 stock Silverado 5.3

Pretty easy install, perfect time to clean the throttle plate as well! Throttle response feels lighter but no real gain in horsepower or fuel mileage

This throttle body spacer was really easy to install, it took me less then 30 minutes. It also increase my mpg by 3 on the highway and 2 on the city. I could definitely feel a difference in acceleration and low end torque. I say for its price and value, it is definitely worth it for me.

This is not a genuine, product but its an excellent aftermarket copy. Install was fast and easy because I found several install videos online. The instructions are ok but not great. Also the spacer is not marked for air flow direction and could be installed backwards if you are not carful to follow the instructions. So far there is no "whistling" that i hear and there is a notable difference in response and acceleration. Fuel milage is also slightly better. I recommend trying this part with other upgrades. I added it to a 2013 Silverado 4.8L with a high flow muffler and high flow air filter.
