MMS Custom Built Honda J Series Thermostat Housing W/ -16 AN








This is a custom made kit that eliminates the bulky thermostat housing and EGR valve assembly. Our kit makes it simple to run flexable -16 AN Nylon braided hose for easy routing. Please note that a thermostat will no longer be used and there will no longer be provisions for heater hoses. An inline thermostat is available if needed. The egr system will also be deleted.

Our brackets are CNC cut and then fully TIG welded. The replacement tube has two bungs to retain the factory water tempeture sensors and a 1/8" npt fitting to use a aftermarket sensor if needed. This kit also includes a modified water tube that runs under the intake to the water pump. -16 AN male fittings are installed for the water inlet and outlet to the radiator. Core water tube is required if you are not purchasing an engine package from us.

This is a specialty item, so 1-3 weeks lead time is needed.
