Main Line Nitrous Kit 50-150HP

The Nitrous Express Main Line Nitrous Kit 50–150 HP is a direct-port wet nitrous oxide system designed for EFI-equipped engines that seek significant horsepower gains without extensive fuel system modifications. This kit is ideal for both street and track applications, providing reliable and progressive power delivery.

This single-stage wet system injects nitrous and fuel through the intake manifold, allowing tuners to adjust the output from 50 to 150 HP through jetting selection. The included 10 lbs aluminum bottle is designed to withstand the rigors of engine bay environments, featuring a white powdercoat finish that resists corrosion.

This system is perfect for builders aiming for modest power increases on naturally aspirated engines, weekend drag racers, and those looking for transient torque gains. Its universal EFI compatibility ensures it can be integrated across various domestic and import platforms, provided the engine management can support the added fuel demand.
