Snow Performance SNO-15025 Water Methanol Injection Kit Stage 1 Naturally Aspirated Carbureted 4150 Flange

The Snow Performance SNO-15025 is a Stage 1 Water-Methanol Injection System designed specifically for naturally aspirated, carbureted engines with 4150-style carburetor flanges. This complete kit provides a safe and effective method to reduce intake air temperatures and suppress detonation, allowing for more aggressive timing and increased performance.

Key Features:

• Designed for naturally aspirated gasoline engines with carbureted fuel systems
• 4150 carburetor flange mounting (fits Holley 4150/4160 and similar carburetors)
• Water-methanol injection reduces intake charge temperatures by up to 100°F
• Allows for advanced ignition timing and higher compression ratios without detonation
• Complete Stage 1 kit includes pump, reservoir, nozzle, and all necessary hardware
• Progressive controller adjusts injection based on throttle position or boost
• Ideal for street performance, hot rods, and muscle car applications

Water-methanol injection has been proven to increase power output while simultaneously improving engine safety margins. The cooling effect of the water-methanol mixture allows the engine to run more efficiently under heavy loads, making this system an excellent upgrade for naturally aspirated performance engines.
