Snow Performance Stage 1 Boost Cooler – Gasoline, Naturally Aspirated, No Tank, Braided Line (4150 Flange) SNO-15025-BRD-T
Designed for high-compression naturally aspirated V8 engines, this Stage 1 Boost Cooler system from Snow Performance lets you run 11:1 to 13:1 compression (or higher) on pump gas by raising octane levels 20–25 points. The result? Cooler intake temps, reduced detonation risk, and more power with improved efficiency.
Activated via a wide open throttle (WOT) switch, the system injects water/methanol only under full load. Ideal for modified builds looking to stretch fuel budgets by using lower-grade gasoline without sacrificing performance.
Includes a 4150-style carb spacer plate pre-threaded for 1/8" injection nozzles and a solenoid valve to prevent vacuum siphoning.
System Includes:
- SHO (Special High Output) Pump
- 1" Carb Spacer Plate
- Solenoid Valve to prevent siphoning
- WOT Activation Switch
- Two nozzles to support a wide horsepower range
- Complete installation hardware
- Note: Reservoir not included with this kit
