Klotz Coxoc 1 Gallon KL-614

If you're serious about extracting every tenth of a horsepower from your engine without major machine work, Klotz Coxoc delivers measurable power gains through proven fuel chemistry. By enriching your fuel mixture with additional oxygen, this concentrate improves combustion efficiency and allows more gasoline to burn per power stroke—yielding consistent 7% horsepower increases across your entire power band. The result is sharper throttle response, improved low-end torque, and acceleration gains that don't come with the heat buildup or instability of other performance additives.

HOW IT WORKS: Mix 1 gallon of Coxoc with 4 gallons of pump gasoline, then tune accordingly—plan for a 2-jet lean adjustment and 1–2 degrees of timing retard to optimize your engine's new efficiency. No oils, no alcohol compatibility issues, and unlimited shelf life when stored above 55°F. Fair warning: avoid this product in California due to local regulations, and keep it away from nitrous systems where freezing can occur.
