Reduces Pinging & Knocking while Increasing Horsepower

Royal Purple's Max-Boost Octane Booster & Stabilizer is a great fuel additive for high-performance engines. It is perfect for carbureted, port fuel injected, and direct injection systems. It also works with nitrous, turbocharged, and supercharged applications.

Max-Boost is specially formulated to raise octane levels by up to 30 points (or 3 numbers) while restoring horsepower and fuel economy. It reduces engine power loss due to harmful deposits from fuel injectors. Max-Boost delivers the best octane enhancement to help eliminate engine-damaging detonation, pre-ignition, and "knocking" from low-octane gasoline.
