Snow Performance Stage 1 Boost Cooler – Naturally Aspirated, No Tank, Nylon Line (4500 Flange) SNO-15035-T
Designed for high-compression naturally aspirated V8 engines, this Stage 1 Boost Cooler system from Snow Performance helps you run 11:1 to 13:1 compression ratios (or higher) on pump gas by increasing octane levels by 20–25 points. The result: cooler intake temps, reduced detonation risk, and more efficient power delivery.
Activated via a wide open throttle (WOT) switch, the system injects water/methanol only under full load conditions. Ideal for performance builds looking to stretch fuel budgets by using lower-grade gasoline without compromising output.
Includes a 4500-style carb spacer plate 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 broad horsepower range
- Complete installation hardware
- Windshield Washer Reservoir Bung
