Product Description
ICT Billet Extended Length LS 1/8" NPT to M12x1.5 Coolant Temperature Sensor Adapter
Adapt 1/8" NPT Temperature Senders to LS Cylinder Head Ports | Extended-Length Design for Aftermarket Gauges
The ICT Billet Extended Length Coolant Temperature Sensor Adapter allows seamless installation of a 1/8" NPT coolant temperature sending unit into the factory LS cylinder head sensor port. Designed specifically for aftermarket gauges and LS engine swaps, this extended-length adapter accommodates sending units up to 1.375" long—making it compatible with a wide range of popular temperature sensors. Featuring precise M12-1.5 threads for direct fitment into Gen III and Gen IV LS cylinder heads, this adapter ensures a secure, leak-free seal. CNC-machined from aerospace-grade billet aluminum, it provides exceptional durability and reliability for high-performance applications.
