Snow Performance Stage 1 Boost Cooler System – Gasoline, Naturally Aspirated w/ Tank & Nylon Line (4150 Flange) SNO-15025
Unlock the power potential of your high-compression naturally aspirated V8 with pump gas. This Stage 1 Boost Cooler system from Snow Performance raises octane by 20–25 points, enabling compression ratios from 11:1 to 13:1 (or higher) without detonation. Cooler intake temps and increased knock resistance translate to more horsepower and improved efficiency.

- SHO (Special High Output) Pump
- 1" Carb Spacer Plate
- Solenoid Valve to prevent siphoning
