200-617 Throttle Body Spacer Replacement for Airaid 2007-2013 Chevrado Silverado1500 Tahoe/Avalanche 2007-2014 Chevrolet Suburban/Cadillac Escalade/ESV/EXT 2007-2013 GMC Sierra 1500/Yukon

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.

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

The product is good quality but if you have a cold air kit installed you can skip a step.

Installed in under an hour, did loose .02 or so mpg but could also be because I need to change my spark plugs. Performance does seem improved. Needs different color options

I'm kind of bummed that I couldn't tell any difference in performance. It didn't help my gas mileage, but didn't hurt it either. I'm really not sure it was worth getting. But, it makes the transition smoother from the throttle body to the intake housing. I didn't hear any difference in airflow noise during acceleration or driving. I'm running it on an 09 Chevy Avalanche, high flow air filter (not a CAI because these vehicles flow enough with the factory intake system.) 3" cat back exhaust with new high flow 3" in/out cat.

Works really good with my cold air intake from R&L racing.

It took less then 20 minutes to install and i did notice better throttle response when taking off form a stand still.

After changing all I could to help my mileage it still wasn’t helping until I took this off and gas mpg increased 3mpg not worth it and no noticeable power gains

I haveing a issue I disconnected the negative battery Disconnected the throttlebody to clean it added spacer but I don’t know if I’m installing it the Proper way It doesn’t have directions on witch way it goes in, my truck is revving up and won’t come back down….

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.
