This spacer comes in thicknesses from 1/4" to 1".
This spacer works in the vehicles listed and helps reduce the heat of the air coming into the engine via reducing thermal conduction, by being a heat insulator. Engines get very hot and this heat transfers through all metal physically connected to it. These spacers can make a noticable difference in that heat transfer, allowing the incoming air to stay closer to ambient (or below in certain forced-induction setups ), since they are installed between the engines and parts of the intake.

Insulating spacers have been around for decades and are proven to help, as they block some of the extreme heat generated by the engine from the intake plenum/supercharger/throttle body to help provide a cooler and more consistent air temperature, which results in better power.

Modern engines run extremely hot for emmissions reasons and can greatly benefit from spacers. All of our spacers are now made out of Garolite G-11 (for superior chemical resistance and heat resistance / insulation), so the color will be light green as shipped. Beware of cheaper spacers than may not withstand the extreme conditions under the hood of modern vehicles or block as much heat transfer.

Since this spacer can fit many combinations (vehicles, makes, and engines), please verify that there will not be any clearance problems arising from moving intake or throttle body out the thickness of the spacer. The best decrease in temperatures will come from using the thickest spacer that the vehicle can fit.

Some spacers may cause alignment issues of other items on or around the engine. Please ensure that this spacer will not cause any issues before purchasing.

We recommend buying an extra stock gasket from your local parts store, and sandwiching the spacer between two stock gaskets. RTV or equivalent sealant can also be used (especially on narrow, thin spacers).

If you need a spacer not shown on the site, let us know and we can quote it for you.
Almost any item here can be customized to better fit your needs. Extra charges may apply, but we will do our best to make it happen. Please contact us for details.
