Designed with noted drag racer Billy Glidden, stainless steel Edelbrock/Glidden E2 Nitrous Nozzles are used in Victor and Super Victor Direct Port nitrous kits and are capable of as much as 500+ horsepower gains in V8 engines using a single-stage direct-port injection system. This exclusive, patented Edelbrock/Glidden design precisely atomizes the nitrous and fuel mixture for consistent and accurate power gains with 5 to 20 lbs. of fuel pressure. Replace your outdated nozzles with E2 nozzles, they're a direct bolt-on upgrade for other brands that use a 90° 1/16" NPT design.
