The LS Steam Port Crossover Kit is designed for GM LS-series engines, providing a connection between the cylinder head steam ports as part of the engine's cooling system. Featuring billet aluminium adapters and a stainless steel braided hose, this kit offers a tidy solution for LS engine conversions, hot rods, muscle cars and custom vehicle builds.
Steam vent plumbing helps release trapped air and vapour from the upper areas of the cylinder heads, supporting proper coolant circulation and cooling system operation.

LS Engine Steam Vent Plumbing
Correct steam vent plumbing is an important part of an LS engine cooling system, particularly when installing an LS engine into a hot rod, classic Chevrolet, custom pickup or performance vehicle.
The LS Steam Port Crossover Kit provides a practical alternative to factory-style steam vent tubing where the kit's fittings and routing suit the engine configuration.
Installation must provide an appropriate coolant return path and maintain clearance around the intake manifold, cylinder heads and surrounding components.
Important Fitment Information
- Not compatible with FAST 102 intake manifolds.
- Check cylinder head steam port configuration before ordering.
- Confirm clearance with intake manifolds and cylinder head fasteners.
- Check the required coolant return connection and hose routing.
- Verify compatibility with your particular LS engine generation and installation.
