Nitrous Express 15137 Pumpless Direct Port Water Methanol Injection System 8 Cylinder

The Nitrous Express 15137 Pumpless Direct Port Water Methanol Injection System is engineered for 8-cylinder engines demanding precise, even water/methanol delivery. Unlike traditional pump-based systems, this setup uses a pressurized reservoir and pressure regulator to push the water/methanol mixture through the system, eliminating the need for an electric pump and reducing potential failure points.

By injecting the water/methanol mixture directly into each individual intake runner, this system achieves superior distribution compared to single-point injection setups, ensuring every cylinder receives a consistent, measured charge for maximum detonation suppression and intercooling effect.

Key Features:

• Pumpless design uses pressurized reservoir and pressure regulator — no electric pump required
• Direct port injection into each intake runner for precise, cylinder-by-cylinder distribution
• Designed specifically for 8-cylinder engines
• Includes braided stainless steel AN hoses for durability and a clean appearance
• Billet machined distribution blocks for reliable flow splitting
• Filtered nozzles help prevent clogging and ensure consistent spray patterns
• Nickel-plated fittings for corrosion resistance and long service life

The Nitrous Express 15137 is an ideal solution for performance and forced induction applications where charge cooling, detonation control, and consistent cylinder-to-cylinder fueling are critical. The complete kit includes all necessary hardware for installation.
