Nitrous Pressure Control Kit w/-4an Adapter

The Nitrous Pressure Control Kit w/-4AN Adapter by ALLSTAR PERFORMANCE is a critical component for any serious nitrous oxide system build. Designed for drag racers, street performance enthusiasts, and tuners who demand precise control over nitrous delivery, this kit manages bottle pressure to ensure consistent jetting and reliable performance across multiple passes. Whether you're running a naturally aspirated engine or a forced-induction platform, maintaining stable nitrous pressure directly impacts repeatability and power output—this controller handles that responsibility.

This pressure-controlled system uses adjustable electronics and relay hardware to monitor and regulate nitrous bottle pressure in real time, preventing over-pressurization and the inconsistent flow that leads to lean-out conditions or detonation. The -4AN adapter port ensures clean integration into your fuel system plumbing without leaks or fitting complications. The compact form factor—weighing just 1.3 lbs and measuring 4.7 x 2.9 x 5.1 inches—allows installation in tight engine bays common to street and race applications. The kit includes all necessary relays and switching hardware for standalone operation or integration with existing engine management systems.

This universal controller suits any nitrous oxide system using standard bottle supply lines and works equally well on carbureted and fuel-injected platforms. Mechanical shops and performance builders rely on ALLSTAR's pressure-control kits to eliminate guesswork and dial in repeatable power gains shot after shot. If you're upgrading an existing nitrous setup or building from scratch and need dependable pressure management hardware, this kit delivers the precision tuning tools professionals use.
