Snow Performance Stage 2 Boost Cooler Methanol/Water Injection SystemThis kit uses manifold boost pressure to determine when and how much fluid to inject. Proportionally injecting according to boost pressure gives the most accurate delivery of water methanol and allows the most cooling and performance improvement over the widest range. More power and driveability is the result. It can be used on any forced induction engine: carbureted, fuel injected, turbocharged, positive displacement or centrifugal blowers. The most
