NOS Powershot Nitrous Oxide Injection System

The NOS Powershot Nitrous Oxide Injection System is a complete, single-stage wet nitrous solution engineered by Nitrous Oxide Systems — the pioneering brand behind more motorsport performance milestones than any other nitrous manufacturer. Designed for carbureted applications, the Powershot line delivers immediate, repeatable horsepower gains with the straightforward installation and dependable quality that NOS is known for worldwide.

Each Powershot kit is built around a proven wet-plate injection design. A precision-machined aluminum injector plate mounts between the intake manifold and carburetor, simultaneously delivering nitrous oxide and fuel enrichment through highly accurate spray bars for a smooth, controlled power surge on demand. The line offers multiple configurations to match different carburetor bolt patterns and performance goals, making it a versatile choice for street performance and strip-ready builds alike.

Key Features:

• Complete single-stage wet nitrous injection system — everything needed for installation is included
• Precision-machined aluminum injector plate with accurate spray bars for even nitrous and fuel distribution
• High-flow nitrous and fuel solenoids engineered for consistent, precise delivery
• Stainless braided AN feed line with leak-resistant AN fittings

NOS Powershot systems represent an outstanding power-per-dollar investment, delivering substantial horsepower increases without the complexity or cost of supercharger or turbocharger installations. Nitrous oxide injection lowers engine intake air temperature, increases the oxygen content of the inlet charge, and increases the rate at which combustion occurs — all contributing to a hard-hitting, repeatable power gain at the push of a button. Whether you're building a weekend street machine or a dedicated drag strip competitor, the Powershot line provides the instant throttle response and proven reliability that only NOS can deliver.
