TracTuff Thermostat Housing Port Adapter for Honda K Series

TracTuff Thermostat Housing Port Adapter for Honda/Acura K Series Engines

The TracTuff Thermostat Housing Port Adapter is the ultimate solution for Honda and Acura K Series engines that demand versatility, reliability, and performance. Designed for builders running custom cooling systems, this adapter makes it easy to retain in-cabin heat with TracTuff swirl pots, clear tight-fitting sidewinder turbo manifolds, or route heater core lines in rear-wheel-drive K swaps where the OEM tube would normally contact the firewall.

Each adapter is precision-machined and engineered to fit perfectly into the factory K Series thermostat housing. It’s available in a 5/8-inch slip hose connection for easy integration with standard heater or coolant lines. The kit includes a -210 O-ring for a leak-free seal, a drill bit, and stainless steel safety wire for secure installation. This thoughtful design ensures a durable, vibration-resistant connection that can handle the heat and pressure of high-performance builds.

Unlike other generic fittings, the TracTuff Thermostat Housing Port Adapter is specifically engineered to function as a return fitting, constantly pulling coolant from the connected system to maintain consistent flow. Whether you’re upgrading your K20, K24A2, or K24A4 engine, or performing a custom K swap, this fitting helps simplify your cooling setup while keeping your system efficient and clutter-free.
