The ignition coil is a fundamental component for the proper functioning of the engine, that's why, your periodic review is extremely important.. A NGK, ignition specialist brand, clarifies five myths and truths surrounding item maintenance.
Worn spark plugs shorten coil life Truth. This is the main cause of ignition coil failures. "Bad spark plugs require more voltage to generate the spark, what, consequently, causes an overload of the entire ignition system, including coils and cables", explains Hiromori Mori, NGK Technical Assistance Consultant.
Whenever the spark plugs are revised, the coils must be checked Truth. "As worn spark plugs can impair the operation of the coils, It is extremely important that the component is inspected whenever there are spark plug failures, to ensure there is no damage", recommends NGK expert.
All coil types require the same test types Myth. Both static versions and individual versions of coils undergo the same types of tests by mechanics during overhauls.. Although, coils that have the integrated ignition module do not perform the resistance test.
Only a visual analysis of the coil is sufficient for the coil inspection Myth. The review of the coils must be carried out in two steps. at first, a visual check is done, where it is possible to detect cracks and cracks in the body of the part and oxidation in the high voltage towers and terminals. In the second step, a measurement of the resistance of the primary and secondary circuit of the coil and the supply voltage is performed. "Coils that have the integrated ignition module do not perform the endurance test", orienta Hiromori Mori.

In case of failure of individual components, all coils must be replaced It depends. When one of the coils has problems, means that, at any moment, the others can also fail. "That's why, It is important that mechanics carry out a detailed analysis of all parts to avoid future customer damage with a new replacement", alerts NGK's Technical Assistance consultant.
