Nitrous Express 20939BMF-15 Nitrous & Water Methanol System with Billet LT4 Supercharger Lid 15lb Bottle

The Nitrous Express 20939BMF-15 is a complete dual-injection performance system featuring a CNC-machined billet aluminum LT4 supercharger lid that replaces the factory lid on GM LT4 superchargers. This advanced lid design increases up to 25 horsepower by itself through improved airflow, with even greater power gains when the nitrous and water-methanol systems are activated.

Billet Supercharger Lid Features:

• CNC machined and anodized in black for corrosion resistance
• Spray bar-less design with nitrous/fuel passages machined into the lid
• Constructed from solid billet aluminum with 1/8NPT ports machined directly into the plate
• Direct port-style injection at each intake runner for optimal distribution
• Compatible with all GM LT4 superchargers for straightforward installation

Complete Nitrous System Includes:

• Billet aluminum and carbon fiber Lightning series solenoids
• Industry-exclusive billet aluminum Lightning 500 bottle valve
• 15lb nitrous bottle with stainless steel mounting brackets
• Stainless steel braided lines and all necessary fittings
• Jetting for 100 to 400 wheel horsepower
• Complete wiring harness and activation switches

Complete Water/Methanol System Includes:

• Billet aluminum and carbon fiber Lightning water/methanol solenoids
• High-pressure electric pump
• NX Stage 2 digital progressive controller for precise methanol output control
• Pre-bent stainless steel hardlines and braided soft lines
• Filtered injection nozzles with nickel-plated fittings
• Composite fluid reservoir
• Complete installation hardware and switches

This comprehensive system includes every component, fastener, and connector required for a complete installation. The dual-injection design allows you to run nitrous alone, water-methanol alone, or both systems simultaneously for maximum performance and engine protection.
