Official Release:
HOLLEY ANNOUNCES NOS OCTANE BOOSTER
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. Over time, this can potentially damage pistons, valves and cylinder walls, NOS Octane Booster facilitates smoother, more stable combustion that expands the safety margin in engines that demand higher-octane fuel.
Features:
- Boost Octane rating up to 5 numbers
- One bottle treats up to 20 gallons of fuel
- Reduces NOX, Hydrocarbon and Carbon Monoxide emissions
- Extends detonation threshold to eliminate engine knocking and pinging
- O2 Sensor safe formula
- Intended for off-road use only
