Construction & Design:

Every component of the Nitrous Express Direct Port Plate System is crafted with precision and quality in mind. The plates themselves are machined from billet aluminum and anodized black to resist corrosion and wear, ensuring long-lasting performance. The 5/8" thickness is engineered to maintain factory hood clearance, eliminating the need for costly aftermarket modifications.

Stainless steel fittings and braided lines provide durability and safety under high-pressure conditions. The system’s design focuses on delivering nitrous and fuel evenly to each cylinder, which improves combustion efficiency and reduces the risk of engine damage. Proudly made in the USA, this kit reflects Nitrous Express’s commitment to quality and performance.

Performance & Sound

By injecting nitrous oxide directly into each cylinder’s intake port, this system significantly boosts horsepower and torque, resulting in faster acceleration and improved overall engine performance. The direct port method ensures a smooth and consistent power curve without the lag or uneven distribution sometimes experienced with throttle body or single nozzle systems. While the system enhances power, it maintains the factory engine sound characteristics, allowing you to enjoy the natural growl of your Hemi-powered vehicle.
