Methanol Injection

Methanol injection (or, more precisely, water/methanol injection) cools the air/fuel charge mixture flowing into the intake of your Subaru, allowing higher boost pressures, more aggressive ignition timing, leaner fuel, or a combination of all of those.  The result is higher horsepower potential for your Subaru motor. Note that custom ECU tuning is a MUST with any methanol injection installation.
