Proton Plus EFI Nitrous System - 35 to 125HP

The Nitrous Express Proton Plus EFI Nitrous System is a wet-injected single-stage performance kit engineered to deliver 35 to 125 horsepower gains across a broad tuning range. This universal EFI-compatible system pairs a 10-pound pressurized bottle with staged jetting capability, allowing drivers to scale boost incrementally from conservative street power to full track aggression without swapping hardware. The wet-injection architecture injects nitrous oxide and fuel atomizer directly into the intake manifold, ensuring uniform distribution and reliable ignition across varying engine loads and RPM ranges.

The Proton Plus system integrates seamlessly with modern electronic fuel injection, eliminating the carburetor tuning complexity of legacy nitrous kits. The 10-pound bottle provides sufficient reserve for multiple full-throttle passes at a given stage setting, critical for consistent dyno validation or consecutive drag strip runs. The stageable design—selectable from 35 HP to 125 HP per activation—allows operators to establish a safe baseline, verify system integrity, then progressively unlock higher output as confidence builds. Dry-line isolation and quality brass fittings minimize corrosion and vapor loss, extending system service life.

This kit suits EFI-equipped vehicles requiring bolt-on power without engine modification or ECU flashing. Track-focused builders, performance enthusiasts, and weekend racers choose the Proton Plus for its reliability, tuning flexibility, and the precision metering that modern fuel injection demands. Buyers comparing nitrous systems for street or strip duty will find the stageable 35–125 HP range eliminates the need for multiple kits across different power objectives, reducing total cost of ownership while maintaining flexibility as performance goals evolve.
