Nitrous Express 90009-12 SX2 Dual Stage Direct Port Nitrous Kit 8 Solenoid 200-1200HP with Composite Bottle

The Nitrous Express 90009-12 SX2 Dual Stage Direct Port Nitrous System is an 8-cylinder gasoline nitrous kit capable of delivering between 200 and 1,200 horsepower. At its core is the patented NX Shark SX2 nozzle — the world's only dual-stage, single-nozzle design — which delivers two fully independent stages of nitrous through a single intake port nozzle, eliminating the need to drill double sets of holes in your intake manifold.

The SX2 nozzle's single-nozzle-per-runner design dramatically reduces turbulence in the natural airflow path compared to traditional multi-nozzle setups. Each SX2 nozzle is capable of delivering up to 300 horsepower per nozzle, configurable in either single or dual stage operation, giving tuners maximum flexibility across a wide range of power levels.

This direct port system is engineered for optimal cylinder-to-cylinder distribution, ensuring even nitrous and fuel delivery across all eight cylinders for consistent, reliable power gains.

Kit Includes:

• 12 lb. composite nitrous bottle
• Stainless steel bottle mounting brackets
• 8 patented SX2 dual-stage nozzles
• 8 aluminum/carbon fiber Lightning solenoids
• Stainless steel hard lines
• Jetting
• All necessary electrical components (switches, wiring, fittings, mounting hardware)

Key Features:

• Dual-stage single nozzle: Two independent power stages delivered through one nozzle per cylinder — no double drilling required
• Up to 300 HP per nozzle in single or dual stage configuration
• 8 aluminum/carbon fiber Lightning solenoids for fast, precise actuation
• Reduced intake turbulence with only one nozzle per intake runner
• 200–1,200 HP power range for broad tuning flexibility
• Lightning solenoids feature an integrated purge port for purge valve connection

Note: Installation requires drilling and tapping of the intake manifold. Professional installation is recommended.
