This thermostat adapter kit is for the Honda K-Series engines that are fitted in a rear wheel drive setup.
This adapter rotates the OEM thermostat to face forward toward the radiator to allow for easier routing of the lower radiator hose.
It is designed to work with the OEM Honda 19301-RAF-004 thermostat and maintains OEM functionality.
IMPORTANT NOTES:
-This kit ONLY works with the OEM Honda 19301-RAF-004 thermostat or replacements similar to it. See photo below.
-Minor disassembly of the OEM thermostat is required.
-You will need to reuse your OEM Honda thermostat mounting bolts or similar M6x1.0 replacements (These will not be provided).

This is a must have if you’re doing a rwd k series. Get to keep OEM tstat housing while being able to rotate it to help with coolant hose positioning. 5/5 would buy again.
