Intercooling - M90 Phenolic Spacer

Includes:

  • 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.

Great product

I ordered the GenV 1/4. Showed up with a bunch of other parts I ordered. Only issue is it came with only one gasket instead of 2. I contacted ZZP and let them know so hopefully another garlock gasket will be coming soon. I've ordered arnd 3k worth of parts from ZZP and one missing gasket is the only issue I've had so far. I'm very pleased with this company and there products, customer service, shipping, packaging all that. LMR for my Mustang. ZZP for GTP

Looks good

The 2nd longest bolt (by the boost bypass valve) could be a bit longer. Also it would be nice if they weren't hex sockets.

Keeping my cool

I decided to get the 1/4 spacer because I didn’t need to change my injection rails to get it to fit. Very easy to install

Insulator

Most excellent product! Installed it along with a 3.4 inch pulley and was extremely satisfied with the results. BIG boost in Boost and power. Now I want to go for you 1.0 PCM asap. Scanned before working and after, never saw more then 2 degrees KR under the hardest acceleration going up hill, all appears to be cool so far.
