Snow Performance Stage 1 Boost Cooler – Naturally Aspirated, No Tank, Braided Line (4500 Flange) SNO-15035-BRD-T
Designed for high-compression naturally aspirated V8 engines, this Stage 1 Boost Cooler system from Snow Performance lets you safely run 11:1 to 13:1 compression ratios (or higher) on pump gas by boosting octane levels by 20–25 points. Expect cooler intake temps, improved detonation control, and increased power output.
The system activates under wide open throttle (WOT), injecting water/methanol only during full-load conditions. Perfect for modified builds looking to stretch fuel budgets by using lower-grade gasoline without sacrificing performance.
Includes a 4500-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 injection nozzles to support a wide horsepower range
