Unleash your engine's true potential with Racegas octane booster that transforms ordinary pump gas into high-performance racing fuel! This case of 4 cans gives you plenty of concentrate to boost your fuel's octane up to 100-105 AKI (that's the good stuff serious racers use). Unlike other boosters that only raise octane a few points, Racegas also increases the chemical BTU energy to match real racing fuel - crucial for preventing lean conditions at wide-open throttle. It's safe for oxygen sensors and catalytic converters, and it uses the Anti-Knock Index measurement that actually matters under load (not just at idle like some products). Whether you're into offroad racing, track days, or just want maximum performance from your street vehicle, this concentrate delivers professional-grade results. The blend chart makes mixing easy, and the concentrated formula means you're not paying to ship mostly carrier fluids. If you're tired of engine knock, want more power, or need consistent performance from pump gas, Racegas gives you race-track performance from regular gasoline. Your engine will thank you with smoother operation and more power when you need it most!
