M90 Phenolic Spacer
- Phenolic Spacer Plate
- 2 gaskets
- 10 longer bolts
This is a phenolic spacer plate that installs between the intake manifold and supercharger. It acts as a heat barrier to lower the temperature of the supercharger which gives you a lower temperature, denser air charge, and more power. There are two different versions and two different thicknesses. You must chose the correct version for your generation supercharger, and you must chose the thickness that best suits your application. We highly recommend you verify that you have enough hood clearance before ordering one. If hood clearance is a problem, an easy way to gain some extra hood clearance is by adding our 1/4" cradle spacers.
Since the fuel rail sits directly over top the supercharger this phenolic spacer will raise the blower up and possibly cause the rail to not be able to bolt back down. The 1/4" unit should fit without any custom work, however the 1" version will require fuel injector spacers. If you have our billet logs you will not have any issue.
These will also work along with an intercooler, the s/c bolts will just have to be the correct length. The bolts that come with them are the correct length for no intercooler.
These will not work on NA (non supercharged) L36/L26 setups.
