    -4AN LS Steam Tube Adapters

  • Specifications:

    Manufacturer's Part Number:

    Specifically designed for the LS series engine, these steam tube lines and adapters compliment aftermarket intakes and accessories that the factory rigid brazed hard lines will not. The lines are designed to eliminate trapped air and steam from your engine to prevent hot spots and overheating. The adapter O-ring seals and converts to -3 or -4 AN plumbing. These Holly Steam tube adapters are the most adjustable and lowest profile available. They look as nice as they are easy to install. Multiple variations available to allow optimal routing on your application which eliminates the need for T adapters. The complete kits are available to plumb all four corners of your LS engine and include the appropriate hoses and hose ends for ease of instillation.

  • Eliminates trapped air, hotspots and overheating
  • Seals to engine with captured FMK O-ring.
  • Adjustable in fitting and hose plumbing path.
  • Upsized from OE tube sizing to -3 or -4 AN.
  • Can be used for front only or front/rear applications

  • Some parts are not legal for use in California or other states with similar laws / regulations
