This 1 inch thick throttle body spacer works with the 2.8L V6, such as equipped Pontiac Fiero GT's. The spacer is installed between the intake manifold and the throttle body, where the throttle body gasket is located (shown as #3 in the picture below).

The cooler throttle body will also help keep the power level stay more consistent. Most cars feel slightly sluggish on very hot days, or after a lot of stop-and-go driving. Part of this is because of the intake air becoming warmer. These spacers will help stop this power loss. This works even better in combination with completely blocking of the throttle body coolant line.

This spacer can also be used as a spot to tap a nitrous line. By tapping in the spacer, no permanent hole is placed on the manifolds, for future sale or warranty work.

I 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.

This Pontiac Fiero 12 inch Corvette Brake Upgrade Aluminum Caliper Bracket Set consists of (2) front adapter brackets and (2) rear brackets.

Each is CNC water-jet from a solid piece of 6061 Aluminum. 6061 is a strong Aluminum alloy with traces of Titanium and Chromium, which makes it the common choice for applications such as aircraft and aerospace components, bicycle frames, driveshafts, and brake components. Its weight is roughly half that of steel, and will not rust.

These brackets allow 1985 Corvette front calipers to fit on the 12 inch rotors, and 1988-96 Corvette rear calipers to fit the rear.

The holes for the front brackets are M-12 x 1.5mm. This is the same thread used other places in the brake system.

These brackets are sold as a kit for $100, for all (4) brackets shipped.

When changing over to the Corvette brakes, 12 inch stock Corvette rotors are used in place of the small, non-vented Fiero ones. The rotors have a different I.D. (inner diameter) than that of the Fiero's. This presents a problem as the rotor I.D. is designed to barely fit over the hub, so that it is perfectly centered, avoiding clearance problems with the caliper.

This fit also makes sure that there is not any side load on the lug studs. Finally, a non-centered rotor would have the same effects as a non-balanced wheel (noise, vibration, and possibly excess tire wear).

To correct this problem, Cheetah offers concentric rings to fit over the hub and match the I.D. of the Corvette rotor.

This motor mount set includes (2) Delrin mounts for the engine side of the "dogbone" brackets that act as upper, engine-side motor mounts.

In stock form, there are round rubber bushings on the end that attaches to the engine, as shown in the picture below. These stock mounts allow quite a bit of movement, which is not the best for performance or for driving vibration.

These Delrin replacement bushings are each made of two pieces of Delrin, connected with a 6061 Aluminum tube to act as a wear bushing for the bolt.

These mounts will help quicken up shifts, along with the many options for the square mounts on the other end of the dogbones. The car will also be more responsive, as the motor does not lose as much torque into the mounts.

Once on the car, it looks stock, unless one knows what to look for. Installation takes about 30 minutes and can be done with a basic socket set and hammer.

Cheetah's 3800 cold-air intake pipe fits in place of the stock intake box and tubing. The pipe is made from a single piece of 3.5" mandrel-bent 304 Stainless Steel. This pipe attaches to the stock rubber pipe on the throttle body, and puts the air filter in the fender area. This area gets the coolest air, and has become a favorite of many Grand Prix owners.

The large diameter of this pipe requires opening of the fender hole. This can be accomplished by bending back the metal sheet. The filter and pipe can be taken on and off of the car as a unit with the plastic splash guard off.

Any K&N style air filter can be used, as long as the flange ID is 3.5 - 4 inches, to properly tighten on the pipe. The filter that we recommend is the SB R0817. This is the filter shown in the pictures with the chrome cap.

The stock Air Temperature Sensor location can be maintained, but we recommend putting the sensor in the pipe near the filter. This will stop the sensor from getting heat-soaked from the engine, which will make the sensor read a higher temperature than actual temperature of the incoming air. This could possibly pull back the timing, which robs even more power. Cheetah recommends putting the sensor in the fender area of the pipe, about 1 inch downstream of the air filter.

The Grand Prix Store sells an extension for this sensor, but I just cut and wired my own extension.

Also shown to the left is the splash guard that I run on my Grand Prix. It is simply a piece of Aluminum bent at a 90 angle and has had two holes drilled into it. These holes allow it to be fit between the bumper and fender guard, and bolted in between as shown. This helps keep the filter clean and dry, and a guard is recommended for everyday driving.

This intake also removes much of the clutter on the driver side of the engine bay. The stock airbox is quite large, since it holds a large flat filter and the PCM.

The PCM can be held down with a GM part made for 2001 Chevrolet Blazers. This can be bought from any GM dealer as p/n 15995679.

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.

We recommend buying an extra stock gasket from your local dealer, and sandwiching the spacer between two stock gaskets. The GM p/n is 24504789.

This 1 inch thick intake spacer is designed for the LQ1 3.4L DOHC V6 engine. The engines that are compatible with this spacer will have the intake manifold as shown to the left. This spacer fits between the upper and lower intake manifolds, as shown with number 72.

These spacers will also add volume to your plenum, which will help increase torque throughout the powerband. Also the longer runners will help high-end power by straightening the airflow towards the cylinder at a farther distance from the valve, allowing it to gain momentum.

Insulating spacers have been around for a long time, and are a proven performance item.

This spacer is 1 inch thick to provide as much insulation as possible, while still having hood clearance. Installation of this spacer is very straightforward, and is the same process as changing the stock gasket.

I 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.

This Aluminum bushing is for manual transmissions only.

Please check your vehicles clutch pedal to make sure that it is a match. There are two types of clutch pedals, so one will need to verify that the vehicle in question has a bushing.

The stock bushing can wear over time, making it impossible to press the clutch in. If (and when) the stock bushing wears out, it can not only make it hard to engage the clutch, but it can completely deteriorate, causing the loss of a clutch completely during driving (trust me on this one!). This bushing also gives the vehicle more precise clutch engagement.

This bushing set consists of one bushing, along with proper e-clip to fit in the retaining ring to prevents the bushings from ever sliding out.
