Earl's Gen III Hemi Supercharger Intercooler ManifoldThe Supercharged Gen III Hemi engine has a relatively large intercooler manifold on the back of the supercharger. The factory manifold may cause clearance issues in an engine swap into a classic muscle car or truck. The Earl's manifold is shorter and provides an additional 1. 875" of clearance and allows the use of AN hoses for the coolant. Billet aluminum construction with black anodized finish.
