2004 Toyota 4Runner Throttle Body Spacers

What Do Throttle Body Spacers Do?

Are you looking for a cost-effective modification to boost your ride’s performance? Then consider installing a throttle body spacer, offering dyno-proven power increases, heightened efficiency, and improved throttle response from a simple, bolt-on product. 

Throttle body spacers are precision-cut billet aluminum spacers installed between the throttle body and intake manifold. Aside from the natural benefit of increasing intake manifold volume, these spacers feature unique curvatures and cuts that increase the velocity of air entering the intake manifold, thus filling the combustion chambers with more high-velocity air, which optimizes combustion and increases efficiency! As we all know, more efficiency means more power and throttle body spacers are no exception to this rule. 

Other benefits of throttle body spacers are their quick and easy bolt-on installation, compatibility with other performance modifications, and cost-effectiveness.

Are Throttle Body Spacers Effective?

While throttle body spacers won’t provide your ride with mind-blowing, throw-you-back-in-your-seat level gains, these products undoubtedly bolster efficiency and power. Throttle body spacers, on average, add between 5-10 wheel horsepower with notable driveability improvements in the mid-range powerband. When paired with other performance modifications, you can expect this number to increase!
