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.
