Product Description

The Nitrous Express 20955-10 is a purpose-built wet plate nitrous system designed specifically for 1986-1993 Fox Body Mustangs equipped with the 5.0L HO pushrod V8. The billet aluminum Spraybarless plate takes the place of the factory EGR spacer, sitting directly between the throttle body and intake manifold for a true bolt-on install with zero cutting or drilling required. A direct-plug-in fuel line adapter is included so there's no need to splice into the factory fuel lines, keeping installation clean and straightforward for both street and strip builds.

With included jetting covering 35 to 250 wheel horsepower in a single stage, this system gives Fox Body owners a wide range of tunability right out of the box. The WOT activation switch ensures the nitrous only fires when the throttle is fully open, protecting the engine under partial load. The 10 lb white powder-coated bottle, Lightning 500 billet aluminum bottle valve, stainless bottle brackets, and all wiring and hardware are included for a complete, ready-to-run installation. This kit is ideal for GT, LX 5.0, and Cobra Fox Body owners who want a clean, reliable, and high-performing nitrous setup built specifically for their platform.
