Extreme 100

Extreme 100 is designed to increase horsepower in unleaded, computer controlled, late model vehicles. It also works very well in 4 stroke motorcycles, street rods, muscle cars, jet skis and boats. Its high (R+M)/2, 100 octane rating gives maximum protection against detonation to 12:1 compression ratio with aluminum heads. Extreme 100 does not contain lead, is CARB compliant and will not harm catalytic converters or oxygen sensors.
