Product Description

The Nitrous Express 20716-15 nitrous system is engineered specifically for late-model Nissan and Infiniti performance cars, including the 350Z, 370Z, G35, and G37. Designed as a direct-fit dual nozzle system, it delivers significant horsepower increases by injecting nitrous and additional fuel directly into the intake tract. The kit includes a large 15 lb nitrous bottle with a Lightning valve to help maintain steady pressure, along with selectable jetting options for 35, 70, 100, and 150 HP gains out of the box. With supplemental jets available, this system is capable of supporting up to ~300 wheel horsepower, making it ideal for enthusiasts seeking big gains without the complexity of standalone forced induction.

Installation is simplified with a direct-plug-in fuel line adapter (no cutting required) and an Autolearn TPS switch that only arms nitrous at wide-open throttle, enhancing safety and throttle response. The inclusion of robust Lightning series solenoids, stainless-braided lines, and a complete hardware kit ensures durability and reliable performance under repeated use. Whether you're upgrading a street car for occasional track use or building a dedicated race machine, the NX 20716-15 provides a well-rounded nitrous solution tailored for these popular Nissan/Infiniti platforms.
