Special Features

  • ​Aerospace-Grade Stainless Construction: Machined from 304 stainless steel per ASTM A276 standards resisting 1500°F exhaust heat and galvanic corrosion outperforming aluminum adapters in high-stress swaps
  • Zero-Leak Thread Precision: CNC-cut M16/M12 to 1/8 NPT threads validated under CMM inspection to <0.05mm deviation ensuring 250 PSI oil-tight seals
  • Full LS Engine Coverage: Compatible with oil pressure ports behind LS1/LSX/LS3 intakes and coolant sensors on 4.2L-6.2L passenger-side cylinder heads
  • Damage-Proof Installation: Annealed copper crush washers flatten at 18-22 ft-lb torque eliminating head fracture risks from over-tightening common in aluminum units
  • Complete Swap Solution Kit: Includes M16x1.5 & M12x1.5 adapters with ASTM B152 copper washers for immediate sensor integration

Description

Precision-Engineered Adapters for GM LS Engine Swaps​ Upgrade your LS engine build with corrosion-resistant stainless steel adapters designed to withstand extreme engine bay conditions. This dual-spec kit enables seamless sensor integration by converting M16x1.5 and M12x1.5 ports to universal 1/8 NPT threading—eliminating compatibility gaps during swaps. ​Material Advantage​ ​Aerospace-Grade Stainless Steel: Precision-machined from 304 stainless steel (ASTM A276 compliant) for 5x higher stress resistance than aluminum alloys. Resists exhaust heat up to 1,500°F (815°C) and prevents galvanic corrosion when paired with iron blocks. ​Laser-Validated Threads: CNC-cut threads undergo coordinate-measuring machine (CMM) inspection to ensure
