The MPG MAX Stage 3 Boost Cooler is unmatched for increases in Fuel Economy AND Power in water-methanol injection systems. Key to this is accuracy and adjustability designed into the system.

The Stage 3 Boost Cooler is unmatched for accuracy and adjustability in water-methanol injection systems. This system can be used on any forced induction engine, or ANY engine with a traditional EFI system, and features our LCD display with on-the-fly adjustability.

This 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.

The gasoline Stage 1 Boost Cooler kit is available for forced induction applications that are either fuel injected or carbureted.
