Product Description

The Snow Performance SNO-40055 is a 1" thick spacer plate that lets you mount a Snow Performance water-methanol injection nozzle on any carbureted engine running a 4500 Dominator-flange carburetor, including Holley, Edelbrock, and Carter units. It's machined with two 1/8" NPT ports and includes the gaskets and studs needed for a clean, straightforward install.

Since it's a universal plate rather than a vehicle-specific part, it works across any Dominator-carbureted build. Just note that mounting the nozzle below the throttle plate requires Snow Performance's solenoid upgrade (#40060) to prevent vacuum siphoning.
