Continuing Innovation:
The Stinger 4 is an addition to the hugely successful Stinger Nitrous Plate lineup and is based on the same ideology that nitrous plates are not one-size-fits-all. It is designed to work with engine combinations that have airflow distribution issues and also have intake manifolds with a taller wall height between the top of the intake runner to the carburetor flange.

Design:
The Stinger 4 is a single-entry nitrous plate that provides a max flow of 644hp. At a glance, the Stinger 4 is very similar to the Stinger 2 - however, the nitrous and fuel discharge port locations have been swapped. The nitrous discharge ports are on top and discharge at a 20¡ angle towards the corner intake runners and a 30¡ angle towards the center intake runners. With the nitrous on top, it sprays down in to the horizontal fuel discharge. On the proper intake, the mixture would contact the base of the plenum wall, just above the port entry. Engine airflow then pulls the mixture into runner, allowing each cylinder to ingest what it wants.

Construction:
The 4150 plate and cone are manufactured from 6061 billet aluminum. The nitrous plate is .75۝ thick and black anodized with engraved Nitrous Outlet logos and Fuel / N2O entry marking. The cone is anodized red and features 16 nitrous discharge holes and 16 fuel discharge holes. Premium gaskets are included as well as Jetting for 50-100-150-200-250-300-350-400-450-500-550-600 horsepower shots. We even include fuel jetting for gasoline and E85 for 5, 7, 10, 45, and 55psi fuel pressures!ÊThis is a race nitrous plate kit and utilizes a and aÊ.Ê This nitrous plate kit comes with our and pre-bent hardlines for the cleanest installation around.ÊÊChoose your nitrous bottle option above.

Application:
The Stinger 4 is designed to saturate 4500 flange single plane intake plenums with a 360¡ downward angle discharge pattern that will not interrupt airflow into the intake plenum. We suggest using the Stinger 4 plate with intake manifolds that measure 1 3/4۝ or more from the top of the intake runner to the flange. This plate is compatible with carburetion or EFI!ÊÊBe sure to measure for boomerang bracket to distributor clearance using the dimensional image above.

Important Note Regarding Nitrous & Pressurised Systems

Orders containing nitrous systems or other pressurised canisters may require additional handling and inspection prior to dispatch.

Due to the nature of these products and applicable transport and state regulations, each system is individually inspected, released, and purged where required to ensure compliance with air and road freight standards. While most orders ship within our normal timeframes, this process may occasionally result in slightly longer dispatch times than those advertised.

We do everything we can to minimise delays, and the vast majority of shipments move through without issue. If you are working to a tight deadline or require urgent delivery, please contact us prior to placing your order so we can confirm the most suitable options.

We appreciate your understanding and patience - this process ensures safe, compliant transport and delivery of your order.

Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase.
