    This carb hat is built for blow-through installations, with a contoured design that promotes optimal airflow and clears most hoods on applications using a 5-1/8" air cleaner flange. A 1/8" NPT reference port gives you a convenient hookup for a boost gauge or carbureted fuel pressure regulator, and the inlet is sized for a 3.5" silicone coupler with a sealing lip for a leak-free installation.

    Specifications:

    • Height: 3.97"
    • Inlet: 3.5" (silicone coupler)
    • Material: Cast Aluminum
    • Finish: Black
    • Gasket Included: Yes
    • Reference Port: 1/8" NPT
    • Fits: Applications with a 5-1/8" air cleaner flange (Sniper EFI, Terminator Stealth, 4150 and 2300 flange carburetors)
