L36 3800 Series II Camaro / Firebird Intake Spacer - $150 shipped

This 1/2" thick intake spacer works 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.

These spacers will also add volume to your plenum, which will help increase torque throughout the powerband, along with the inherit cooling properties. Insulating spacers have been around for a long time, and are a proven performance item.

Installation of this spacer is very straightforward, and is the same process as changing the stock gasket.

Cheetah recommends buying an extra stock gasket (shown below) from your local dealer, and sandwiching the spacer between two stock gaskets. The GM p/n is 24504789.

Cheetah Phenolic spacers are cut from a single piece of Garolite by CNC water-jetting. Garolite is a great heat insulator, and these insulating properties will keep the plenum and throttle body cooler; as it will not absorb as much heat via conduction from the engine. This results in a cooler air-intake temperature, which creates a denser charge that provides more horsepower. A great article on the effects of cooling via spacers can be read here.

The cooler plenum and throttle body will also help keep the power level stay more consistent. Most cars feel slightly sluggish on very hot days, or after a time of stop-and-go driving. This is in part because of the intake air temperature rising. These spacers will help stop this power loss. IN certain applications, these spacers also add volume to your plenum, or smooth out the path to the cylinders, which will help increase torque throughout the powerband.

Spacers are great bang-for-the-buck, proven performance item, especially on an already modified vehicle; while not having any negative side effects like lower gas mileage. Many spacers sold are a fiber phenolic. But all of Cheetah spacers are made from Garolite, which has equivalent insulation properties to normal Phenolic, but is more moisture resistant. This is preferred, since an engine bay can have many different climates, with varying humidity's. Many vehicles also run EGR and PCV vapors back through the intake, and Garolite stands up to this harsh environment; as it is also more chemically resistant. In addition, with a wet nitrous kit, extra injectors, or a water injection kit, there may be considerable amount of fluid in the intake.
