Niterra highlights the care of the ignition system for the proper functioning of the vehicle
São Paulo, January 2026 - Symbol of Brazilian automotive history and national passion, o Fusca é celebrado em 20 de janeiro com o Dia Nacional do Fusca, bringing together generations of admirers, collectors and clubs across the country. To set the date, Niterra, owner of the NGK brand, global reference in ignition systems, reinforces the importance of specific maintenance care, especially the ignition, to ensure the proper functioning and preservation of classic cars.
Despite its recognized robustness and mechanical simplicity,, the Beetle requires special attention, mainly because it is a vehicle that, In many cases, runs less frequently or remains stationary for long periods. Under these conditions, the ignition system takes on an even more important role in preventing failures, premature wear and starting difficulties. Among the main recommended care for Beetles and classic cars, A ngk destaca:
1- Use correct spark plugs within original specifications: It is always important to follow the manufacturer's instructions, respecting thermal degree and suitable application to the engine.
2- Carry out periodic spark plug inspections: even in vehicles that run little, It is necessary to check the wear, carbonization or oxidation.
3- Pay attention to the condition of the ignition cables; to ensure good electrical insulation and prevent electrical current leakage.
4- Check other ignition system components; In addition to wear items such as candles, we should check the platinum, rotor, coil, vacuum advance diaphragm, dynamic advance drive and distributor shaft play. As they have more components, there are a series of inspection and adjustment items.
4- Always keep the ignition system well adjusted: This action contributes to efficient burning of the air-fuel mixture.
5- Avoid components of dubious origin: These parts can compromise engine operation and the integrity of original parts.
6- Prevent fuel aging: in rarely used vehicles, fuel stored in the tank may age. Ideally, the vehicle should be used frequently to avoid fuel aging.. For vehicles that will be parked for a long time, there are specific procedures to avoid fuel aging problems., consult your mechanic regarding the need and necessary procedures.
“In classic cars, preventive maintenance is even more important. An efficient ignition system ensures easier starts, stable operation and helps preserve the engine, respecting the original characteristics of the vehicle. Vehicles with a carburetor tend to cause greater carbonization of the spark plugs., because they work with a richer air/fuel mixture, requiring more specialized labor when maintaining the carburetion system”, afirma Hiromori Mori, Technical Assistance Consultant at Niterra do Brasil. “In the case of the Beetle, the correct spark plug makes all the difference in maintaining the reliability that has made the model an icon.”
Noble metal candles as an option
In addition to conventional candles, Today there are spark plug options with noble metals, such as iridium and platinum for longer screw plugs, which can also be used on Beetles, observing compatibility with the type of cylinder head used in the engine. The engines of these vehicles have two types of cylinder heads., short and long thread, respecting the correct application specifications is essential. Iridium and platinum spark plugs stand out for their thinner central electrode, which favors a more precise and stable spark, contributing to faster starts, more uniform engine operation and better burning efficiency, even in vehicles that remain stationary for long periods.
Another benefit of precious metal candles is their greater durability compared to traditional candles., which reduces the need for frequent replacements, an especially interesting advantage for preserved classic cars. Nonetheless, It is essential that the owner or restorer evaluates the use of this type of spark plug in accordance with the original engine design, always observing the correct thermal degree and appropriate technical recommendation, ensuring reliability without compromising the originality and performance characteristic of the Beetle.
Niterra offers spark plugs with noble metals on the aftermarket market, including iridium and platinum options, developed with the same technology and recognized quality as the NGK brand. These solutions allow Beetle owners and enthusiasts to access modern, reliable components, maintaining care with performance, the durability and preservation of your classic vehicles.
