Snow Performance Gas Carbureted 4500 Flange Stage 1 Water Inj Kit (WOT Activated SS Braided Lines)

Snow Performance is well-known for their water-methanol injection systems, designed to help you get more power and better engine cooling. This Stage 1 kit is specifically built for gas carbureted engines using a 4500 flange intake, like those found on many high-performance street and race vehicles. It works by injecting a mixture of water and methanol into your intake charge. This process cools down the air entering your engine, making it denser, and also increases the effective octane of your fuel. The result is the ability to run more aggressive ignition timing, which directly translates into increased horsepower and torque without the need for extensive engine modifications.

This particular kit is designed to be activated at Wide Open Throttle (WOT), meaning it only injects the mixture when your engine is under heavy load and demanding maximum power. This ensures you're not wasting fluid during normal driving and are getting the cooling and octane boost precisely when you need it most. The system includes a high-output pump, a 3-quart tank for the water-methanol mixture, filtered nozzles for proper distribution, and push-lock lines for easy installation. The stainless steel braided lines add durability and a clean look to your engine bay. It fits directly onto Dominator or 4500 series intake flanges, making installation straightforward for compatible carburetors.

For boosted applications, this system is especially beneficial as it significantly reduces intake air temperatures, helping to prevent detonation and allowing your turbo or supercharger to operate more efficiently. While this kit is activated by WOT, Snow Performance also offers more advanced controllers that can progressively manage output based on boost pressure or vacuum, giving you even finer control over your engine's performance parameters. This kit is a solid option for anyone looking to safely extract more power from their carbureted, forced-induction, or high-compression gasoline engine.
