WINNERS oil filter plays a crucial role in keeping an engine clean and protecting it by removing contaminants from the engine oil as it circulates through the lubrication system. This includes filtering out metal particles that are inevitably generated during engine operation, which helps to prevent engine wear and extends its lifespan.

 The raw materials used in its main products, namely automotive oil filters and fuel filters, are the same as those used in products manufactured by Hyundai Mobis, such as POSCO, Hyundai Steel, and Ahlstrom. The filter paper inside the product maintains sealing efficacy and cleanliness, thereby extending the expected life cycle of the filter. The sheet metal used for the exterior of the product is being managed internally to prevent the surface from rusting due to the recent high temperatures and high humidity. The rubber used for the gaskets, which helps to prevent oil leaks, is manufactured without mixing it with any chemicals.
