CANDLE OS-MAX P4

CANDLE O.S. P4 - hot.

• Heat: warm
• Recommended for off road vehicle engines
• Manufacturer: Os-Max Japan

Definition of candle warm th:

If the engine runs properly on spark plug A, and after replacing it with spark plug B, a needle is required to reach full - even rpm (depleting the mixture) it means that spark plug A is warmer than spark plug B. Candle B requires the supply of additional heat from the combustion of a more depleted mixture to achieve optimum operating temperature.

Correct selection of candle warmth allows for an increase in RPM by up to 2,000 RPM, correct adjustment of the mixture composition to guarantee high power and engine durability, and allows to improve the so-called "transition" when changing revs. A candle that is too cold causes a decrease in power and a bad "transition". A candle that is too hot causes premature ignition, engine heating and detonation combustion, which can contribute to damage to the candle.

CAUTION!!! The supply voltage of the plug should not be higher than 1.4V. Otherwise, there will be destruction (burning) of the candle. If the candle is supplied from a battery with a higher voltage (e.g. 2V), use an additional resistor or resistance wires to reduce the voltage.
