Construction & Design

Built with high-quality materials and attention to detail, the Nitrous Express Fly By Wire Nitrous Kit features stainless steel components that resist corrosion and withstand the rigors of performance driving. The solenoids are designed for lightning-fast response times, ensuring immediate nitrous delivery when activated. The system’s wiring harness and sensors are engineered for compatibility with factory electronics, minimizing the risk of faults or errors. The included bottle bracket is crafted from stainless steel to provide a secure, vibration-resistant mounting point that maintains bottle integrity under demanding conditions.

Performance & Sound

By injecting nitrous oxide directly into the intake system, this kit significantly increases oxygen availability, allowing your Hemi or SRT8 engine to burn more fuel and produce substantially more power. The result is a noticeable surge in acceleration and throttle response without compromising drivability. The system’s precise activation via the drive-by-wire throttle ensures smooth power delivery, avoiding abrupt or unpredictable surges. While the kit primarily enhances power, the added combustion intensity may also produce a subtle increase in engine sound and exhaust note, contributing to a more aggressive driving experience.
