Description

Nitrous Express Proton Fly By Wire Nitrous Kit w/5lb Bottle

Proton Series nitrous systems combine performance, durability and value in a compact and easy to mount module. Proton systems contain high quality, made in the USA, solenoids that are capable of producing 150 horsepower to the wheels. The black anodized aluminum housing not only looks great, it pulls heat away from the solenoids for extreme durability. This Proton fly by wire system includes jetting for 35HP, 50HP, 75HP, 100HP, 125HP and 150HP. This system comes complete with a 5lb nitrous bottle with an aluminum high flow Lightning 45 bottle valve, stainless bottle brackets, a single Shark nozzle, nozzle adapter, stainless braided nozzle lines, extra long braided stainless feed line, stainless fuel line, master arming switch, 40 amp relay, relay harness as well as every nut, bolt and electrical connector needed to complete the installation. This system includes a TPS Autolearn wide open throttle module for use with all electronic fuel injected vehicles, including those with 'fly by wire' electronic driven throttle bodies.

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.
