TAKUMI PINIRIDIUM spark plug, opening a new era of high-end quality!

How long will a spark plug last?

A Even when a spark plug is correctly used, periodic replacement is required as it is a consumable item.

In addition to correct heat rating, what other precautions should be taken durin

A Ensure the spark plug has the correct thread reach. The engine will not operate properly without the proper thread reach. If a spark plug with the wrong thread length is erroneously used, the piston or valve could strike it and damage the engine. Moreover, there is also the concern that the electrode could overheat and melt

Is there a specified tightening torque for the spark plug

Q15 Is there a specified tightening torque for the spark plug A The tightening torque for a spark plug changes with the diameter of the spark plug. The following are the recommended torque values.

Is a stain between the insulator and metal shell caused by gas leakage?

A It is not a stain caused by gas leakage but by corona discharge (corona stain).

What is good ignitability?

A "Ignition performance" refers to an engine's ability to successfully and effectively, burn a wide range of air/fuel mixtures. A good spark plug can improve "Ignition performance"

What are the effects of spark plug overheating?

A Prolonged overheating may induce abnormal combustion such as pre-ignition and detonation resulting in melting of the spark plug electrodes and damage of engine.
