NOS Showerhead Distribution Block - Nitrous & Fuel Port Injection

NOS Showerhead Distribution Blocks are a critical component for any serious multi-port nitrous system, engineered to deliver balanced, simultaneous distribution of both nitrous oxide and fuel to every intake port. Whether building a high-powered street machine or a dedicated race application, these distribution blocks provide the consistent, even flow characteristics that keep power output predictable and engine internals protected.

Key Features:

• Low-profile showerhead design — refined into a compact, user-friendly form factor that simplifies installation and routing
• Parallel inlet/outlet orientation — allows for a more compact installation of nitrous solenoid feed lines, reducing clutter and improving overall system layout
• Precision-profiled internal passages — engineered to maximize flow and minimize pressure drop, ensuring equal delivery to every outlet port simultaneously
• Aircraft-grade aluminum construction — lightweight yet strong alloy provides excellent durability under the demands of high-pressure nitrous and fuel delivery
• Corrosion-resistant anodized finish — professional surface treatment delivers a clean appearance and long-term protection
• Multiple outlet configurations available — product line spans a range of inlet and outlet port counts to accommodate various engine layouts and cylinder counts
• Fittings sold separately on select variants — allows full customization of plumbing configuration for your specific application

In a multi-port nitrous setup, uneven distribution of nitrous or fuel to individual cylinders can cause dangerous power imbalances and serious engine damage. NOS Showerhead Distribution Blocks address this directly with internally profiled passages that meter flow evenly and simultaneously to every port — delivering consistent power across the entire RPM range and peace of mind for both street enthusiasts and professional racers.

NOS (Nitrous Oxide Systems) has been at the forefront of nitrous technology since the late 1970s and has powered more racers to victory than any other nitrous brand. These distribution blocks reflect that same commitment to precision engineering and real-world performance that has made NOS the benchmark in the industry.
