Nitrous Express 63940-10 Single Entry Crossbar Plate System Flange Bottle - 250-650HP 4150 with 10lb

The Nitrous Express 63940-10 is a premium single entry billet crossbar nitrous plate system designed for 250-650 horsepower applications. This system delivers the proven crossbar spray pattern in a competition-legal package that uses only one nitrous jet and one fuel jet, making it ideal for racing classes with strict injection restrictions.

Advanced Crossbar Design:

Unlike traditional spray bar systems, this billet aluminum plate features an integrated crossbar design with no spray bars to sag, rotate, or disrupt airflow. The result is consistent nitrous distribution and unobstructed air passage for maximum performance and reliability.

Lightning 500 Bottle Valve Technology:

Includes a 10lb nitrous bottle equipped with the innovative billet aluminum Lightning 500 valve. This high-performance valve features dual integrated gauge ports, a 5/8" siphon tube, and a massive .500" orifice. The optimized flow path with only one 45-degree turn maximizes flow efficiency while weighing nearly a full pound less than traditional brass valves.
