CSF B58 Thermal Rejection Competition Spacer (For Super Manifold 8200)

Heat from the cylinder head soaks into the intake manifold, and that warms the charge air before it ever reaches the engine. CSF's spacer sits between the head and its B58 Super Manifold to block that heat path, aiming for lower manifold and intake air temperatures and less heat soak. CSF says it is especially useful in drag and roll racing, where cars idle in staging lanes with little air moving over the front heat exchanger.

What you get

• 6.5 mm spacer made from KIYLEX, a patented polymer that CSF says is as strong as aluminum.
• Heat resistance up to 1100°F, per CSF.
• Self-sealing design, with no gaskets, silicone or sealant needed.
• Installation hardware and instructions included.

Good to know

• Works only with the CSF B58 Super Manifold. It will not fit the factory manifold.
• CSF designed it for motorsports use where maximum cooling is the goal.
