Edelbrock Direct Port Nitrous Systems


DIRECT PORT NITROUS CONFIGURATION AND FEATURES
Our most sophisticated nitrous systems allow you to tune each individual cylinder for superior performance! Utilizing your choice of either Edelbrock E1, Edelbrock/Glidden E2 stainless steel, our unique E3 titanium "Straight-Shot" nozzles, or Stainless Steel Dry nozzles for EFI applications, these direct port nitrous kits are designed for serious competition with power increases of up to 500 horsepower or more. To build a new system, match these kits with an Edelbrock Bottle Kit for maximum race-level performance with the bottle/bracket combination you want. For racers with an existing system, our manifold Plumb Kits include everything to plumb a manifold only (no wiring harness, relays, or thread tap).

Four different nozzle designs make Edelbrock Direct Port Nitrous Kits among the most versatile competition systems on the market today. Three designs use a 90° outlet configuration for ease of installation and plumbing, and our unique E3 titanium nozzle features a patented "Straight-Shot" configuration with an in-line discharge. With thread sizes of 1/8" NPT or 1/16" NPT, there's an Edelbrock nozzle for every racing application, whether you're building a new system or replacing outdated competitor's nozzles.
