Improved Racing’s Front-Sump LS oil cooler adapter

New and improved! Improved Racing's front-sump LS oil cooler adapter has been completely redesigned with several improvements:

  • Now fits both front and rear sump applications! Perfect or rear sump applications that require bottom exit lines.
  • New single-piece design with custom edge-bonded Viton rubber gasket is more reliable and less prone to leaking.
  • Now lighter and more compact.



The adapter features an 1/8″ NPT port for an oil pressure or temperature sensor, or for a turbo oil supply line. It's machined from 6061-T6 billet aluminum and is anodized for durability. Features standard female -08AN O-ring boss threads for optional anodized adapter fittings in your choice of -08AN, -10AN or -12AN lines.



The optional bracket relocates the hard power steering line out of the way of the adapter in front sump applications such as the Pontiac GTO and Holden VT-VZ platforms. This is a 100% bolt-on solution; no fabrication, bending or line modification is required.
