Harrop LS TVS Supercharger Thermal Spacers

$114.99

Harrop LS TVS Supercharger Thermal Spacers is a Harrop thermal-isolation upgrade designed to reduce heat transfer into the supercharger assembly.

On supercharged engines, heat conducted from the cylinder heads and manifold can contribute to higher supercharger and intake-air temperatures, particularly in low-speed and stop-start operation. Harrop thermal spacers create an insulating barrier at the relevant mounting interface to help reduce heat soak and support more stable intake temperatures.

Purpose: reduce conductive heat transfer into the supercharger/manifold
Application: refer to the specific Harrop supercharger/engine configuration
Recommended: confirm compatibility with the exact manifold and cylinder-head combination

Built by Boost & Tune can confirm the correct Harrop spacer application and provide workshop installation support.
