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
