Earl's – GM LS Oil Pressure Gauge Adapter Fitting (-4 AN) for GM LS Engines

Upgrade your GM LS engine swap with the Earl's GM LS Oil Pressure Gauge Adapter Fitting, designed for precise fitment and reliable gauge installation. This adapter threads directly into the factory M16 x 1.5mm oil passage at the rear of the LS engine block, allowing easy integration of aftermarket oil pressure gauges. Built from durable 2024-T8 aluminum with a blue anodized finish, it offers superior strength compared to standard 6061-T6 fittings while resisting corrosion in high-heat environments. Engineered for performance and versatility, this adapter is compatible with a wide range of gauge setups, including mechanical hoses and aftermarket sending units. Whether you’re building a street car, race setup, or custom swap, this fitting ensures a secure and leak-free connection.

Features:

  • Direct-fit M16 x 1.5mm connection for GM LS engine blocks
  • -4 AN male port for aftermarket hose and gauge setups
  • Blue anodized 2024-T8 aluminum for superior durability
  • Ideal for installing aftermarket oil pressure gauges
  • Lightweight corrosion-resistant construction
  • Compatible with other M16 x 1.5mm plumbing applications
