- Meets or exceeds OEM safety and durability standards!
- This spark plug has met OEM performance standards, with an extended lifespan and powerful performance.
The need to replace spark plugs: - Spark plugs made of different materials have clear replacement cycles, with nickel alloy spark plugs at around 20000 kilometers, platinum spark plugs at around 40000 kilometers, and iridium spark plugs at around 60000 to 100000 kilometers. If the vehicle's mileage approaches or exceeds the corresponding standards, it needs to be prepared for replacement.
- In addition, the appearance status can also be used to determine whether replacement is needed. If a large amount of severe carbon deposits are found on the surface of the spark plug during disassembly, resulting in severe electrode wear and melting, insulation cracking, erosion scars, and black patterns, it means that you need to replace the spark plug in a timely manner.
- If your vehicle experiences difficulties with cold start, severe engine shaking at idle, weak acceleration, increased fuel consumption, abnormal exhaust emissions, etc., it is highly likely that the performance degradation is caused by lax quality control of spark plugs or prolonged use, and requires inspection and replacement.

 " To confirm that this part fits your vehicle, enter your vehicle's Year, Make, Model, Trim and Engine in the eBay Compatibility Table. " The importance of spark plug selection: - Spark plugs made of different materials have different differences in various aspects. The choice of materials represents the quality of the product, whether it has a long service life, and whether it can bring you greater benefits.
- MODIGT spark plugs are made of high-quality iridium, which has much higher wear resistance than ordinary materials such as nickel alloy. Its service life can reach 60000 to 100000 kilometers or even longer, while ordinary nickel alloy spark plugs can usually only be used for about 20000 kilometers. This means that using our spark plugs can significantly reduce the number of replacements, lower maintenance and replacement costs, and comprehensively improve economy.
- In addition, our spark plugs have super high hardness and extremely high melting point due to their inherent material characteristics. Able to work steadily in a high temperature environment for a long time. Generate high-intensity and stable electrical sparks. Even in harsh working conditions such as low temperature and high altitude, it can quickly ignite the mixture in the cylinder, reducing the risk of stalling or accidental ignition. Small electrode gap between 0.4 to 0.8 mm Allows for more precise and focused spark formation,resulting in improved combustion efficiency and optimize combustion process.
- Our spark plugs can adapt to various types of engines, whether they are family sedans or performance cars, and can stably perform in different driving scenarios such as daily commuting and high-speed cruising. They have a wide range of applications and are easy to install. After installation, it can maintain stable performance even in harsh working environments, with a much lower probability of failure than ordinary spark plugs, bringing you a perfect driving experience every time.
 - In addition to materials, we have the most advanced manufacturing technology that enables stable spark delivery and reliable start-up and acceleration. Powerful and effective in reducing misfires and carbon deposits, with reliable durability, maximizing engine health protection, ensuring a quiet and maintenance free experience.
- The focused flame core can achieve faster combustion, while the conical center grounding electrode can reduce energy absorption， Improving vehicle acceleration performance, reducing operating noise, enhancing driving experience, and achieving comprehensive improvement by promoting full combustion of fuel and reducing unburned pollutant emissions in exhaust.
- Therefore, MODIGT is different from other ordinary spark plugs on the market. We will show you the best performance and equipment, with long-lasting use, wear resistance, and will bring you the highest quality experience.
- MODIGT spark plug, your best choice.
