The NX Stage 1 EFI nitrous system is the top of the line EFI power booster on the market. From the billet aluminum and carbon fiber solenoids, to our patented Shark nozzle, this system screams nothing but quality.This system includes a single Shark nozzle, nozzle mounting bung, Lightning series solenoids, 3AN stainless braided solenoid to nozzle lines, 4AN stainless braided nitrous feed line, 4AN fuel feed line, nickel plated fittings, wide open throttle switch, master arming switch, 40 Amp relay, relay harness, 1/4 inch fuel line T, stainless bottle brackets and systems with a bottle include the Lightning bottle valve.

This system includes the latest technology and the best components available. NX Lightning solenoids feature an improved flow path that eliminates sharp turns and expansion areas in the nitrous flow path. This keeps the nitrous in dense liquid form which makes more power on less nitrous. Lightning nitrous solenoids feature an integrated purge port which allows you to connect a purge valve directly to the body of the nitrous solenoid for clean looks and less plumbing. Lightning Series solenoids feature CNC aluminum bodies topped with Carbon Fiber cans for the ultimate in weight savings.
This system includes a 10lb nitrous bottle with the billet aluminum Lightning 500 bottle valve. This valve not only looks great; It is packed with features including two integrated gauge ports, 5/8 siphon tube, a large .500 orifice and an improved flow path with only one 45 degree turn. The Lightning bottle valve looks great, flows great and weighs nearly one full pound less than our old style brass valve.

Pretty Colors to Encourage Me to Walk!
Size: X-Large, Color: (601) Bittersweet Pink / Stone / Stone
Hum. Extra large does not seem extra large. I have a slender but size 10-10.5 foot. Will keep but was hoping for a looser fit. Bought to match an Under Armour walking outfit.
