NEW: NOS OCTANE BOOSTER

Higher Octane, More HP & Better Fuel Economy

NOS Octane Booster can provide the extra edge you need when the chips are down. Like pouring Nitro in your gas tank, it allows forced induction engines to run more boost safely, so you don't encounter the engine's detonation threshold. It's also especially beneficial in high-performance, turbocharged and high-compression engines running on a track day. This single-use fuel additive boosts octane up to 5 numbers, which aids in reducing knocking or pinging during combustion. Engine knock occurs when the fuel/air mixture ignites prematurely, leading to retarded timing and a drop off in engine performance and fuel efficiency.
