These LSA/LS3 spacer plates bolt in-between the intake manifold/supercharger and cylinder head to reduce heat transfer between the supercharger and engine. This in turn reduces supercharger induction temperatures by decreasing heat soak from the engine. This will increase the thermal efficiency of the supercharger and will provide more HP gains due to the decreased temperature of the condensed air entering the cylinder. These 10mm thick spacers are manufactured from an engineering thermoplastic with low thermal conductivity properties. Please check clearance in engine swapped applications as this will raise the intake 10mm. Comes complete with bolts and o-rings.
