WEAPON-X: Direct Port Meth 1.9L Lid Spacer [CTS V, Camaro ZL1, LSA]
Vendor: WEAPON-X Motorsports
Without the spacer in place, overboosted vehicles will experience a choke inside of the Supercharger lid. Turbulence causes friction and heat, thus decreasing the thermal efficiency of the compressed air. By inserting the lid spacer, the air calms down allowing the passage through the Supercharger without the unwanted turbulence. The result is a more efficient factory brick supercharger.
The supercharger lid spacer is cut out of 6061 aluminum plate using a CAD file on a water jet. It increases plenum volume 63 cubic inches. Kit includes lid spacer, brick spacer and elongated bolts, Permatek is required for installation on surfaces without OEM gaskets. Strut bar spacer available upon request for additional cost, it is not needed for the ZL1 but is needed for the ZL1 lid on a CTS V. So if you are ordering for the ZL1, please note this in the comments when placing your order.
