Nitrous oxide is the easiest way to add big power to any engine and NOS is the #1 name in nitrous! NOS is proud to introduce a new nitrous solenoid to the lineup. The NOS Pro-Bigshot™ nitrous solenoid features a huge .250" orifice encased in a lightweight, clear anodized billet aluminum base that provides maximum flow for extreme applications. The Pro-Bigshot™ is a pressure balanced design that greatly reduces power draw, requiring only 4-6 amps during operation. Coming in at only 3.5" tall and 1.63" in diameter, the Pro-Bigshot™ nitrous solenoid makes installation easier on multiple stage systems compared to the trash can style solenoids.
