As part of the Aeroflow Performance GM LSA program we introduce these thermo plastic intake spacers. These Intake spacers are designed to suit your GM LS3 style heads allowing you to bolt on the GM LSA supercharger or simply can be bolted on to your GM LSA engine. Being a thermo plastic material you also get the added benefit of reduced heat transfer with the supercharger no longer sitting directly on top of the cylinder heads but sitting an extra 10 mm above. This will raise the blower assembly up 10mm so be sure to check your bonnet clearance for conversion cars and new bolts are provided for installation.
