This intake spacer was created to work with the 3800 Series II RWD engine in the Pontiac Firebird and Chevrolet Camaro. The spacer is installed between the lower and upper intake manifold, where the intake gasket is located.
The GM p/n for this gasket is 24504789.
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.
Standard shipping charges will apply to the rest of the world.
