Snow Performance design and developed the Boost Cooler Stage-2.5 water/methanol injection systems for 2015+ Subaru WRX, it suppresses detonation so that more power-producing timing can be utilized. Water, with its high latent heat of vaporization, cools the intake charge and combustion. Methanol cools the charge and combustion, but also acts like an extremely high-octane fuel (some researchers claim as high as 120 octanes) and adds more oxygen to combustion. Also, this Stage 2 Boost Cooler is complete with a custom water-methanol injection throttle body spacer plate, braided stainless line, and 4AN fittings offering unsurpassed reliability and ease of install. They're designed for use in naturally aspirated carbureted gasoline vehicles.
