The Story

Stainless LS Engine Sensor Adapters: M16/M12 to 1/8 NPT
✔️ Kit includes M16x1.5 / M12x1.5 adapters with copper washers

This CNC-machined stainless steel kit converts LS engine sensor ports from M16x1.5 and M12x1.5 to 1/8 NPT, enabling coolant temperature and oil pressure sensors across LS1, LSX, LS3, 5.3L, 6.0L and 6.2L engine swaps.

✅ Aerospace-grade 304 stainless steel construction per ASTM A276 for heat and corrosion resistance
✅ CNC-cut M16x1.5 & M12x1.5 to 1/8 NPT threads with <0.05mm deviation to ensure 250 PSI oil-tight seals
✅ Full LS engine coverage: oil pressure ports behind LS1/LSX/LS3 intakes and coolant sensors on 4.2L-6.2L heads
✅ Annealed copper crush washers flatten at 18-22 ft-lb to prevent head fracture, even in high-torque swaps
✅ Complete swap solution kit includes both adapters and copper washers

💡 What is a sensor adapter kit used for in engine swaps? This handy device helps you connect sensors to LS engines with mismatched ports and sizes. - Handy for coolant temperature and oil pressure sensor connections. - Durable stainless steel resists heat and corrosion in engine bays. - Includes copper washers for leak-free, reliable seals
