Distribution Blocks

The Nitrous Oxide Systems Distribution Block is a precision manifold component engineered for builders and tuners running dedicated nitrous oxide systems on high-performance engines. This aluminum distribution block serves as the central hub where a single nitrous feed line splits into multiple controlled outlet ports, allowing simultaneous fuel and nitrous delivery across multiple cylinders or fuel injectors. Whether you're building a street strip car, bracket racer, or carbureted nitrous application, this block is essential infrastructure for safe, even distribution of nitrous flow throughout your engine.

Manufactured from lightweight aluminum and finished in hard-anodized black, the distribution block features a single 1/8 inch NPT female inlet port that accepts nitrous supply line from your solenoid valve, with four 1/8 inch NPT female outlet ports for individual cylinder or fuel circuit connections. The NPT (National Pipe Thread) female configuration accepts standard aftermarket fittings, allowing customizable plumbing based on your specific engine layout and delivery strategy. Black anodizing provides corrosion resistance while maintaining a clean, professional appearance under the hood—critical for systems subject to moisture and temperature cycling inherent in nitrous applications.

This distribution block works best in systems where four-point distribution is required, making it ideal for V8 engines running four-cylinder nitrous nozzle kits, eight-cylinder carbureted platforms needing dual-feed capability, or fuel-injected applications requiring isolated nitrous circuits per bank. Installation involves basic plumbing with appropriate 1/8 NPT fittings and Teflon tape; secure mounting near the engine helps minimize line length and potential heat soak. Compact dimensions (3 x 1.05 x 4.05 inches) and minimal weight (0.07 lbs) mean installation flexibility without adding significant mass or complexity to your nitrous package.
