Frequently Asked Questions

Q: What does a supercharger adapter set do? A: It provides a mounting interface that allows a supercharger assembly to be positioned on a cylinder head whose intake bolt pattern or port layout would otherwise not accept it directly.

Q: How should fitment be verified? A: Compare the complete existing cylinder head part number and supercharger part number, along with the full engine and vehicle model designations, against the applications listed before purchase.
