4 Port Low Profile Steam Kit

The ICT BILLET 4 Port Low Profile Steam Kit is a precision-engineered coolant distribution system designed for GM LS-series engine builds. This four-corner aluminum steam vent kit provides efficient coolant circulation management across the engine block, eliminating air pockets that compromise cooling performance and reliability during high-output engine operation.

Constructed from aluminum with black anodized finish, the kit delivers corrosion resistance and thermal stability essential in modern engine bays. The low-profile design minimizes clearance conflicts with intake manifolds and accessory drives common on modified LS platforms. Each of the four corner ports features purpose-engineered fittings and hose barb connections that accommodate standard coolant hose diameters, allowing integration into both OEM and custom cooling circuits without modification to engine block ports or water pump inlet configuration.

This steam kit addresses a critical need for LS engine builders, street car enthusiasts, and performance shops working with crate engines or block-and-brisket builds. Forced air and carbureted applications particularly benefit from active coolant bleed-off, as does any build where the OEM thermostat housing has been relocated or deleted. The compact footprint fits tight engine compartments while the modular design allows selective port usage depending on your specific cooling circuit topology.
