A throttle body spacer will insulate your TB from the heat of the supercharger. Keeping your TB cool will help keep your intake temperatures down thus reducing KR and increasing HP potential.

The inlet is 72mm to work great with stock or our ported throttlebodies.

Great product

Purchased the throttle body spacer hoping to help with the known knock issue. Noticed drop in boost but overall did feel a better throttle response and louder supercharged. Also got my throttle body heat shield in today looks awesome as always zzp #1 with great product and customer service

Great piece

Installed with my ported TB and immediate difference in throttle response and sound. Very nicely cut piece and installed quickly and with no fitment issues. Highly recommended.

Throttle body spacer

Have yet to have a nice enough day to really dig under the hood and install it but so far looks like good quality at least!! And of course fast shipping and great customer service!

Throttle Body Spacer

Works well, nicely cut, I like the way it blocks off the coolant passages to the throttle body. seems to do its job.

Perfect fit.

Bought this with the heat shield. Adds a nice look to the engine bay and works great with aftermarket throttle bodies. Didn't see a drop in kr but noticed about 5 degree cooler intake temps. Every little bit counts!
