Nitrous Express 66147-00 Dry Single Entry Billet Crossbar Plate System Flange - 100-500HP 4500

The Nitrous Express 66147-00 is a high-performance dry nitrous plate system designed for serious power gains on 4500-style intake manifold flanges. This single entry billet crossbar plate delivers reliable nitrous distribution for applications ranging from 100 to 500 horsepower increases.

Key Features:

• Precision-machined billet aluminum construction for durability and optimal flow
• Dry system design—nitrous only, fuel enrichment handled by your existing fuel system
• Single entry crossbar configuration for even distribution across all cylinders
• Compatible with 4500-series carburetor/throttle body flanges (Dominator pattern)
• Adjustable power range from 100 to 500 horsepower with proper jetting
• Direct bolt-on installation between intake manifold and carburetor/throttle body

This kit includes the billet crossbar plate assembly with integrated nitrous distribution but does not include a nitrous bottle. The dry system design makes this an ideal choice for EFI applications where additional fuel can be supplied through the existing fuel injection system. Professional installation and proper tuning are recommended to ensure safe operation and maximum performance.
