15# Replacement Bottle

The NOS 15# Replacement Bottle is a 15-pound nitrous oxide bottle engineered for high-performance automotive applications requiring reliable, consistent nitrous delivery. Built by Nitrous Oxide Systems—a manufacturer with decades of experience in forced induction systems—this aluminum bottle features a Hi-Flo valve designed to maximize flow rates and system responsiveness. The blue paint finish provides corrosion protection and easy identification in the engine bay.

At 21.2 pounds and measuring 8.5 x 8.3 x 32.6 inches, this bottle delivers adequate nitrous capacity for both street and moderate track use while maintaining a compact footprint suitable for most engine compartments. The Hi-Flo valve arrangement reduces restriction in the nitrous supply line, allowing faster spool-up and more linear power delivery compared to standard valve designs. The aluminum construction provides durability while keeping overall weight minimized—a critical consideration in performance vehicles where every pound affects acceleration and handling balance.

This replacement bottle is ideal for enthusiasts upgrading their existing nitrous system, refurbishing equipment after extended use, or building a new dry nitrous installation from scratch. Whether you're running a light street tune, weekend bracket racing, or developing a more aggressive forced induction setup, having a dedicated replacement bottle on hand eliminates downtime between fills and ensures consistent system operation. The 15-pound capacity represents the sweet spot for applications ranging from mild bolt-on engines to moderately modified power plants.

NOS bottles of this size and specification are industry-standard across the performance market, meaning compatibility with most mainstream nitrous kits is assured. Verify your specific kit's bottle connection and pressure requirements before purchase to confirm this unit matches your system's specifications.
