The supercharger being in direct contact with the cylinder heads and sitting directly over the valley of the engine reduces thermal efficiency and heat is always the enemy in positive displacement superchargers.

With the Thermal reduction plates the blower will operate significantly colder, reducing heat soak and increasing consistency. The air entering the combustion chamber will average lower temps and be denser, allowing a HP gain and when tuning more ignition timing thus again more HP.

The plates suit LS3, L77, L98, LSA, LS9, LS1,LS2 style cylinder heads the brand of supercharger will not matter, the plates are 10mm thick and will raise the blower up by 10mm so check to see if you have enough hood clearance & a longer belt may also be required. Check Before Ordering.
