Construction & Design:

Crafted entirely from billet aluminum, the direct port plates are precision-machined to exacting standards and anodized black for a sleek appearance and superior corrosion resistance. The 5/8" thickness ensures structural integrity while maintaining a low profile that fits neatly under the factory intake manifold. Stainless steel fittings and braided lines provide robust connections that withstand high pressure and heat, ensuring long-term reliability.

The system’s design focuses on delivering nitrous oxide and fuel directly to each cylinder’s intake port, promoting even distribution and efficient combustion. This approach reduces the risk of lean conditions and engine damage compared to single nozzle or throttle body plate systems.

Installation & Fitment:

The Nitrous Express Direct Port Plate System bolts directly under the intake manifold, making installation straightforward and minimizing the need for extensive modifications. Its design maintains factory hood clearance, eliminating the need for aftermarket hoods or significant engine bay alterations.
