Want modern engine technology with an old-school look?
Our billet aluminum throttle-body adapter creates a carbureted look while allowing you to benefit from a drive-by-wire throttle-body and EFI. This unique product requires a GM Gen-IV 4-bolt 90mm throttle-body (standard on LS2, LS3, LS7, etc.), an LS 4-barrel carburetor intake manifold and manifold-specific fuel rails. Schwartz Performance can supply everything you need to complete this retro intake conversion.
Just mount a MAF above the throttle body and fabricate an adapter to mount a drop-base air cleaner.
Includes hardware to mount to intake manifold.
