Description

Holley EFI carburetor hats are the perfect complement to any blow-through installation. They feature a contoured design that promotes optimal airflow, while providing excellent hood clearance for most applications. Each hat has a 1/8 in. NPT reference port that can be used as a suitable hookup for boost gauges or carbureted fuel pressure regulators. The inlet is designed for a 3.50 in. silicone coupler (unless otherwise noted), with a sealing lip to ensure a leak-free installation. EFI aluminum carb hats are available in a natural or black powdercoat finish.
