Nitrous Express 4150 Assassin Plate Stage 6 Alcohol 50-300HP (w/o Bottle)

Assassinate the competition with the Assassin plate system. The Assassin is the most technically advanced single stage plate ever designed. The CNC machined design integrates the nitrous and fuel discharge ports into the outer perimeter. The Assassin offers a unique perimeter spray pattern that assures perfect nitrous-fuel distribution. Which in turn solves the problems commonly found on single plane manifolds, particularly small and big block Fords. This new innovation provides superior distribution and outstanding atomization. With no spray bars to sag, split, block airflow, or damage this is the Next Generation in nitrous plate technology.

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.
