Has anyone installed a throttle body spacer on their Challenger? Some claim it will improve low-end torque and horsepower, and even increased fuel efficiency. Any truth to any of this? :scratchhead:

A throttle body spacer doesn't do anything from a performance standpoint. All the claims are snake oil. However, if you would like to purchase a bridge I may be able to help you. :D

If you are in the market for a spacer, go for the Stack Performance Phenolic Manifold Spacer. It is 1/4" thick and sits in between the manifold and the heads. It does reduce the manifold temperature down by at least 20 degs relative to the core temperature.

A throttle body spacer is a waste.

X2 - Stack Performance Phenolic Spacers. Go ahead and order the better option ones ($20), I think. One of the best low buck mods you can do for your car, IMHO. Right up there with the "Sprint Booster", go for both, I did & I've no regrets regarding either one.

HTH's!
