Nitrous Outlet 4 Wet Nitrous Plate System

The Nitrous Outlet Stinger 4 is a wet nitrous plate system specifically engineered for 4150 flange carburetors, designed to address airflow distribution issues in engine combinations with taller intake manifold walls. This system features a unique design where nitrous discharge ports are located on top, angled towards the intake runners, to create a well-mixed charge pulled into each cylinder. Constructed from .75” thick 6061 billet aluminum, the plate is black anodized with engraved Nitrous Outlet logos and fuel/N2O entry markings. The included cone is anodized red and equipped with 16 nitrous and 16 fuel discharge holes. This kit provides jetting for horsepower gains ranging from 50 to 475hp, with fuel jetting options for gasoline and E85 at various fuel pressures (5, 7, 10, 45, and 55psi). It utilizes standard .122" nitrous and .177" fuel solenoids, connected via braided stainless hoses, and comes with universal solenoid brackets. Premium gaskets and hardware are also included. The Stinger 4 is intended for single-plane intake plenums with a 360° downward angle discharge pattern that does not disrupt airflow. For optimal performance, it is recommended for use with intake manifolds measuring 1 3/4” or more from the top of the intake runner to the flange. This plate is compatible with both carburetion and EFI setups.
