Prevent heat from transferring to the intake manifold, plenum, and throttle body!

Improve airflow by eliminating the need for OEM gaskets, which are not matched to your ports.  All NWP Phenolic Spacers are port matched to your stock intake ports!  A smooth transition from one intake manifold to another is very important for optimal airflow.  Don't be fooled by other "thermal gaskets" made of soft plastic that aren't properly matched to your intake ports!  They are usually just a copy of the OEM gasket.

Port Matched!

Average intake plenum temperature decrease of 40 degrees!

Experience an intake manifold that's cool to the touch!

Our Spacers are made out of a very strong glass based phenolic laminate and can be reinstalled as many times as you want. Never have to buy another intake gasket again!

Guaranteed to outlast the life of your vehicle!
LIFETIME WARRANTY

Can be used along with our 75mm Big Bore Throttle Body Adapter Plate Kit.  Everything is perfectly port matched!

Includes: 

• Two 1/16" Phenolic Intake Manifold Spacers (Lower Intake Manifold) (Spacers go below the lower manifold against the heads)
• 1/16" Phenolic Intake Manifold Collector Spacer (Intake Plenum)
• 1/4" Phenolic Throttle Body Spacer
• 4 Lengthened Zinc Plated Throttle Body bolts and washers (choose if you have the stock 70mm or the NWP 75mm Throttle Body)
• Printed Installation Instructions with Photos (PDF Instructions)
• Two 5"x1" White Vinyl NWP Engineering Decals

The two Lower Intake Manifold Spacers will go below your lower manifold against the heads.  The Intake Plenum Spacer will go on top of the lower intake manifold. The 1/4" Throttle Body Spacer will go between your upper plenum and the throttle body.  If you have the NWP 75mm Throttle Body Kit, this Spacer will go between your upper plenum and the NWP 75mm TB Adapter Plate. A paper thin layer of Black RTV should be applied to both sides of every Spacer to prevent intake leaks according to our installation instructions.
