These are new in the wrapper
Plenum Insulator Kit
Low profile (1/8" thick) phenolic insulator plates assist in plenum temperature reduction, while minimizing the chance of hood interference: plates,and fasteners.

This requires plenum coolant block off

Im curious as to what color these are? Are they still made or is this something that has been discontinued? are these reuseable? sorry for all the questions ! Also if I may just ask as im not personally familiar with that site... do they still sell that thermostat ?

LGAFF · 11-13-2016

They are a brown color, reusable as far as I know

Not sure what SRPs inventory is or if they are selling

Do these plates eliminate the need for gaskets?

LGAFF · 11-14-2016

Will let others comment, I would think they would still be needed, but might be incorrect

No, they do not replace/eliminate gaskets. In fact, two sets of Intake Plenum Gaskets are required when the spacer is used, one on each side. Spacers are reusable.

The photo on SRP's website shows the Throttle Body Heat coolant port is open in the plates. Like our gaskets, they may be deliberately made that way so the plates & our gaskets can be rotated/flipped to block the coolant port if desired. If blocked, it appears SRP also includes a coolant bypass line.

The principal purpose of the spacers was to act as a thermal barrier to heat soak from the engine. To some minor degree, additional clearance on the underside of the plenum may contribute to cooling due to increased airflow.

SRP makes products with outstanding quality. I have long endorsed the SRP longer pressure plate bolts for use with aftermarket, lightweight flywheels in combination with the stock ZR-1 Pressure Plate.

Thanks for confirming the two gasket requirement.

Hey Lee,

How about $75 shipped USPS to my military APO address?

Thanks for your consideration.
