Description

Spark plug for engines of garden equipment and gasoline machinery. Designed specifically for 4T engines, it has a long neck and thermal grade 5. Its technical measurements are: thread diameter 14 mm, thread length 19 mm, 16 mm hexagonal and flat seat. Technical equivalence with the RC12YC reference, which facilitates its direct replacement in compatible engines. A spark plug in good condition guarantees quick starting, efficient combustion and lower fuel consumption. It is recommended to check and replace periodically according to the hours of use of the equipment and whenever starting problems or loss of power are detected. Presentation: pair of spark plugs.

Frequently Asked Questions

What is this spark plug for?

It is a spark plug designed for 4-stroke engines of garden equipment. It is responsible for generating the spark that ignites the air-fuel mixture inside the combustion chamber, an essential condition for the engine to function correctly. It is equivalent to the RC12YC reference, so you can replace your current spark plug if it matches the measurements and thermal rating.

How do I know if this spark plug is compatible with my engine?

To ensure compatibility, you must check that your engine accepts a spark plug with these measurements: 14 mm thread diameter, 19 mm thread length, flat seat and long neck. If your team originally mounts a spark plug with another reference, always verify that the measurements and thermal rating match before replacing it.

What does the heat rating of this spark plug mean?

This spark plug has a thermal grade of 5. The thermal grade indicates the ability of the plug to dissipate heat: a higher grade dissipates more heat and is used in engines that work at high speeds, while a lower grade retains more heat and is suitable for engines that work at lower revolutions. It is important to respect the thermal rating recommended by the manufacturer of your engine.

Does it have a long or short neck?

It has a long neck. The long neck is used in engines with a deeper combustion chamber. It is essential to respect the type of neck indicated by the manufacturer to avoid damage to the engine or ignition malfunction.

How often should a spark plug be changed?

As a general rule, spark plugs in garden equipment engines should be replaced at least once per season or every 50-100 hours of use, although it depends on the type of equipment and the quality of the fuel. Change it sooner if you notice starting problems, loss of power, increased consumption, white smoke or if you see worn, deformed electrodes or black deposits that are not easily cleaned.

What is the technical equivalence of this spark plug?

Its technical equivalence is RC12YC. If your original spark plug has this reference or a compatible equivalent, you can replace it with this model without problem. Before changing it, write down the reference of the current spark plug to always have the correct replacement on hand.
