Snow Stage 4 Boost Cooler Platinum Water Injection Kit – Braided Line SNO-9000-BRD
Attention tuners: Snow Performance’s Stage 4 Boost Cooler delivers OEM-grade fuel system control for precise water-methanol injection across the entire RPM range. This advanced system uses both engine RPM and boost pressure to build a fully adjustable 2D water-methanol map, allowing for exact delivery at any engine load—similar to a standalone ECU.
With the included Platinum Tuning Software (free download), users can monitor live data, fine-tune injection curves, log sessions, and even send completed water-methanol maps to remote customers—all from a laptop while on the dyno. The kit includes a USB cable, pre-terminated wiring harness, LED alert system, and ¼" nylon tubing with quick-connect fittings for streamlined installation.
Recommended for serious tuners who demand full control over water-methanol delivery.
Note: Units purchased from Nitrous Express/Snow Performance after February 1, 2020 are Stage 4 V2 and use updated software that is not compatible with V1 components.
Optional 100 PSI MAP sensor available separately.
