These spacers are made from polytetrafluoroethylene (PTFE also known as Teflon) with integrated glass fibers. PTFE has an incredibly low coefficient of thermal conductivity. The result is a superior heat barrier to isolate the upper intake manifold section from high engine temperatures.

PTFE Spacers are made of 75% PTFE, with 25% glass-fill. They are extremely resistant to heat conduction, water absorption, oil/chemicals, and abrasion. The material is also sandable, meaning the spacers can be ported to match ported intake manifolds. Furthermore, it is self-sealing: no additional gaskets needed!

No Additional Hardware Needed Each spacer comes with bracket spacers to accommodate the greater distance between manifold sections. Longer bolts are not necessary; although stainless bolts (which feature lower heat conduction properties than standard steel) can be optionally purchased.

Tight Tolerances The spacer design was created using sophisticated CAD software to incredibly tight tolerances of less than 0.0015?. Spacers are precision cut using waterjet technology accurate to 0.001? or more.

These spacers were designed for 2.0L 420A Mitsubishi Eclipses, Eagle Talons and Dodge Avengers.
