Phenolic Supercharger Spacer Kit for Audi 3.0L SC
This spacer kit is for Audi B8 S4/S5s with the 3.0L Supercharged engine. It raises the SC up 3/4" of an inch. This clears (barely) the hood with an APR Ultracharger Throttle Body and pipe.
The kit consists of two spacers with o-ring seals, longer studs/washers/nuts to replace the stock bolts, and an adapter to lengthen the oil separator connection to the bottom of the SC.
A belt is not included as there are too many configurations with different sized pulleys. For reference, our test vehicle runs 193/57.75 pulleys and with the spacers uses a 53.6" (3160mm) long belt. A 51.6" (1310mm) belt is used with both stock pulleys and spacers.
While the supercharger is off, it is a great time to clean the intake valves with this kit.
Installation takes a few hours as most (shorter once one has had the SC off as many times as us). The spacers are placed on top of the factory gasket seals and bolted down as shown with the provided studs. The SC itself seals against the o-rings provided. We recommend a little white lithium grease when installing any o-rings. Also place the separator extension on before reinstalling the SC.
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 noticeable 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 emissions reasons and can greatly benefit from spacers. All of our spacers are now made out of Garolite G-10 (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.
Adding a spacer may necessitate the need for longer bolts. Unless specifically stated, these are not included with the spacer.
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 an OEM gasket is not available, we can cut paper gaskets to match the spacer.
If you need a spacer not shown on the site, let us know and we can quote it for you.
