Steam Port Crossover

Steam Port Crossover Kit

Stainless lines

-4 AN fittings / NPT fittings

Aluminum Blocks

This kit will clear most intake manifolds and fit all gen 3/4 LS engines. It ties the rear steam ports to the front steam ports to allow even passageways to the steam port exit. 

Get rid of the rear block off plates, and the “front only” factory steam port tubes along with the throttle body steam port on some models. It’s also looks great on custom builds!
