Did you know that spring demands automotive maintenance to protect ignition coils?

During wetter periods, Simple inspections, that increase the durability of the coils, Avoid engine problems

São Paulo, setembro de 2025 - A chegada da primavera e a transição para uma estação marcada pelo aumento da umidade relativa do ar, in September, It is a factor that directly influences the performance and durability of the vehicle components. Increased humidity may favor oxidation processes, compromise isolations and impair the operation of electrical and electronic components. Among the most susceptible elements is the ignition coil, responsible for generating the tension necessary to form the spark in the combustion system.

Humidity is one of the main enemies of the ignition system. Water infiltration can cause failures, loss of power, increase in fuel consumption and even complete crashes. In this context, and NGK, Niterra brand specialized in ignition systems, shares tips for preventing coil damage and ignition system during spring:

1- Preventive verification: Before the rainy season, Bring the vehicle to a trusted mechanic to inspect cables and candles, since problems in these other components can directly impact coils performance.

2- Infiltration protection: It is necessary, including rubbers, COVERS AND CONNECTIONS, to ensure that they are in good condition and fulfill their function from preventing water and moisture in the engine region. Damage or wear in these components may favor infiltrations that compromise the operation of electrical and electronic systems. Leaves and small twigs can clog the drains, accumulating rainwater or windshield wipers.

3- Quality parts: Use original components of recognized brands to ensure greater durability and resistance.

4- Preventive replacement: If the coil has cracks, Visible corrosion or wear, replace it immediately to avoid engine failures. For coils applied directly to the ignition candles, Check that the terminals are not dry and without elasticity.

Care in maintenance of coils

With the growing demand for reduced pollutant emissions, Ignition coils have evolved significantly, highlighting the use of individual coils per cylinder and high energy, that provide a more efficient fuel burning and better engine performance. Even with these advances, Proper maintenance is essential to ensure its longevity, since worn ignition candles require greater tension to generate the spark, increasing stress on the coils and reducing their service life. To facilitate replacement, NGK provides an electronic catalog and an application for mobile phones, allowing consumers and mechanics to quickly and accurately identify the appropriate coil for each vehicle.

“With spring rains, It is common to increase the number of vehicles that reach workshops with ignition failures. A simple preventive verification can avoid inconvenience, engine failures, that increase fuel consumption, damage to other components, that raise maintenance costs ”, explains Hiromori Mori, Niterra Technical Assistance Consultant

Rapid identification and correction of coil failures is critical to the proper functioning of the ignition system. Recomenda-se a inspeção a cada 10 mil quilômetros ou, at the very least, annually, using functional tests that evaluate the shooting voltage and the signal shape of the signal, in addition to visual inspections to detect oxidation, dry terminals and cracks. For Coils That Have Already Been Committed, and NGK, brand of Niterra, offers the automotive replacement market a wide range of products designed to ensure that engines operate within performance specifications, Economy and emissions.
