throttle body spacers
Has anyone installed a throttle body spacer? Any noticeable performance / mpg improvement ?

You won't get any "seat of your pants" HP gains, but you should get some, and you should also gain a little MPG...

A lot of it also depends on what motor you have in your truck. If you type throttle body spacer into the search bar, you'll come up with tons of posts about them.

been using an Airaid spacer for years. Could definitely feel the difference in response (no so concerned with HP). After running it for over a year, i took it out and tested the truck. I'll never do that again.99 Silverado - Stock

I've noticed a very small increase in fuel mileage, and small increase in off the line, and throttle response, some say it is worth the money, some say it's not, i think it's preference. Don't expect an increase in HP, because if it does, it wont be enough to notice anything.
