Nitrous Express NP603 4150 Single Entry Crossbar Nitrous Plate

The Nitrous Express NP603 is a precision CNC-machined billet aluminum crossbar nitrous plate designed for 4150-style carbureted applications. This single-entry plate represents a significant advancement in nitrous distribution technology, eliminating traditional round spray bars in favor of an integrated crossbar design.

Key Features:

• CNC-machined billet aluminum construction for superior strength and precision
• Integrated crossbar design eliminates problematic round spray bars
• Superior atomization and even cylinder-to-cylinder nitrous distribution
• No spray bars to sag, rotate, or obstruct airflow over time
• Single entry point for simplified plumbing
• Designed for 4150 carburetor flange applications
• Plate-only configuration for custom system builds

This plate-only component is ideal for racers and performance enthusiasts building custom nitrous systems or replacing worn plates in existing setups. The elimination of traditional spray bars ensures consistent nitrous delivery without the maintenance concerns of conventional designs, while the precision-machined passages guarantee optimal fuel and nitrous atomization for maximum power gains and engine safety.
