6AN 4ft Nitrous Line Black

The 6AN 4ft Nitrous Line Black from REDHORSE PERFORMANCE is purpose-built for high-performance fuel and nitrous oxide delivery systems where reliability and precision matter. This hose assembly serves as a critical component in nitrous kits, turbo fuel systems, and custom automotive builds where pressurized lines must withstand extreme conditions without failure. Whether you're tuning a street machine or building a track-focused engine, a quality nitrous line protects your investment by ensuring safe, consistent flow to injectors and distribution blocks.

This 4-foot nitrous line features a 6AN (AN6) fitting specification, the industry-standard size for mid-range nitrous and fuel applications on street and competition engines. The black reinforced hose construction resists degradation from UV exposure, ozone, and temperature fluctuations common in engine bays. REDHORSE PERFORMANCE hose assemblies are manufactured to strict tolerances with properly swaged fittings that eliminate leakage points—critical when pressures exceed 1,000 PSI during nitrous oxide delivery. The integrated design prevents separation at connection points, maintaining system integrity through repeated thermal cycling and vibration typical of modified engines.

This nitrous line suits builders and tuners upgrading fuel delivery or installing complete NOS systems on V8s, turbocharged platforms, and performance street cars. The 4-foot length accommodates most engine bay layouts, routing from remote bottles or fuel cells to solenoids and distribution manifolds without excessive slack. Installation pairs seamlessly with REDHORSE fittings and AN-compatible components; ensure proper routing away from exhaust manifolds and moving parts. Compatibility spans any application using 6AN nitrous or fuel lines—from mild bolt-on kits to full competition setups. For race-proven reliability and professional-grade construction, this REDHORSE line delivers the durability serious enthusiasts demand.
