HARD TO FIND!!

These are the unusual coolant bypass fittings that Mopar used on their small block LA engines from the 60s through the early 90s, and most aftermarket LA intakes. Mopar quit making these, but we still have them! 

These are usually very difficult/impossible to remove from factory intakes and it is difficult to find something to substitute. When you're switching to a new intake, it's best to just get these as well. This includes the 3/4 and 1/2 nipples as shown.

Vehicle & Engine Fitment

  • Engines: Mopar Small Block LA series (273, 318, 340, 360).

  • Years: Primarily 1970–1991 factory and aftermarket manifolds.

  • Platforms: A-Body (Dart/Duster), B-Body (Charger/Road Runner), E-Body (Challenger/Cuda), and Dodge RAM trucks.
