Nitrous Express 15300L Lightning Pro-Power Nitrous Solenoid 500HP 0.125 Orifice

Vehicle Fitment

• Universal - Compatible with any nitrous oxide system requiring a high-flow nitrous solenoid with 1/8" NPT inlet and outlet connections, rated to 500 HP flow capacity

Fitment Notes

• This is a nitrous solenoid only - not a fuel solenoid; verify solenoid type before ordering
• Inlet and outlet connections are 1/8" NPT female threads - ensure your nitrous line fittings are compatible before installation
• Maximum current draw is 33 amps - verify your wiring harness and relay are rated for this draw
• Sold individually - one solenoid per purchase

Features

• Raised inlet and bottom exit design eliminates up to four 90-degree turns and one expansion area inside the solenoid body - keeping nitrous in liquid form longer for maximum power output
• CNC-machined billet aluminum body with color anodized and laser-marked finish for precision, durability, and a premium appearance
• True carbon fiber solenoid can for significant weight savings over conventional steel can designs
• Built-in 1/8" NPT bypass/purge port allows direct connection of a purge valve or fuel return line - eliminates lean spikes caused by trapped air between the regulator and solenoid
• 0.125-inch orifice supports nitrous flow up to 500 horsepower
• Made in the USA using the highest quality solenoid components
• Backed by a 5-year limited warranty against defects in workmanship and materials

Product Description

The Nitrous Express 15300L is the flagship Pro-Power entry in the Lightning Series solenoid lineup - a precision-engineered nitrous solenoid built to maximize horsepower by keeping nitrous in liquid form all the way to the injection point. The key to the Lightning's performance advantage is its unique flow path: the raised inlet and bottom exit design eliminates up to four 90-degree turns and one expansion area compared to conventional solenoid bodies. Every turn and expansion zone in a nitrous solenoid is an opportunity for the liquid nitrous to go gaseous, and gaseous nitrous delivers less power than liquid. By minimizing these disruptions, the 15300L delivers a cleaner, denser nitrous charge and measurably more horsepower at the same jet size.

The CNC-machined billet aluminum body paired with a true carbon fiber can sets the Lightning Series apart aesthetically and practically - the carbon can reduces solenoid weight meaningfully compared to steel alternatives, which matters in weight-sensitive motorsport applications. The built-in 1/8" NPT purge port is a genuine functional advantage: connecting a purge valve directly to the solenoid body eliminates the section of line between the regulator and solenoid where air can become trapped, preventing the lean spike that often accompanies the first activation of a cold system. Rated to 500 HP on a 0.125-inch orifice with a max draw of 33 amps and backed by a 5-year limited warranty, the 15300L is the performance solenoid choice for serious nitrous builds.
