Hybrid Racing Coolant Temp Sensor Adapter - K-series

This useful Hybrid Racing fitting allows you to insert a factory B/D coolant temp sensor into the upper section of the K-series coolant system. This is required since the older generation gauge clusters can't understand the information being sent from the K-series ECU.

Thread the adapter in, screw the coolant sensor in and you'll have a working temp gauge! This adapter replaces the OEM idle air assist valve (not used on K-swaps) leaving you with the perfect spot to thread your sensor into. If you don't want to run a hose insert, this is the piece for you. You're probably thinking, but wait can't I just get any old fitting? NOPE, this port uses a weird thread size so we did all the leg work, designed a new fitting and present it to you here in all of its glory.

Hybrid Racing coolant temp sensor not included but can be purchased HERE.
