Hybrid Racing K Swap Coolant Temp Sensor Adapter

Give your swapped Honda the finishing touch it deserves: the Hybrid Racing K Swap Coolant Temp Sensor Adapter lets your stock dash gauge read perfectly without ugly inline splices or hack-job fittings. When a K-series engine goes into an older chassis (EF/EG/EK/DC/DA, etc.), the factory cluster expects the two-wire B/D-series coolant sender. This precision-machined adapter replaces the unused K-series idle-air assist valve, providing the exact thread pitch for that sender so your temperature needle behaves just like OEM.

Why you’ll love it

Plug-and-play for gauge accuracy – no recalibration, no extra wiring
CNC-machined 6061 aluminum with a hard-anodized black finish that shrugs off corrosion and heat soak
Correct “odd” thread on the engine side and proper B/D sender thread inside—zero leaks, zero guesswork
Eliminates hose-splice adapters, freeing up space and giving your bay a cleaner, factory look
Designed, tested, and backed by Hybrid Racing, the brand that pioneered many of the industry’s most trusted K Swap solutions

What’s in the box

New sealing crush washer

Compatibility

All K20/K24 water necks that originally housed the idle-air assist valve (most K20A/A2/Z1/Z3 & K24A variants). Accepts any OEM or aftermarket B/D-series coolant temperature gauge sensor.
