Box contents - 1 high-quality filter cartridge. No additional locking required; simply place it on the filter unit. The suction cup provides a secure fit for the filter. Performance and benefits - The filter material offers a large surface area for dust and dirt due to its texture and structure. - The material is air permeable, contributing to a sufficient air supply, pure recirculation, and optimal protection of the engine. Care and maintenance - Do not wash the filter. Knocking or blowing out carefully is recommended. - Washing out is a myth and can clog pores and affect performance. - A filter that looks clean can still negatively affect function and place additional strain on the engine. Replacement and longevity - Change filters regularly for full suction power, optimal filtration of the exhaust air, and less effort required from the engine. Key attributes - Material: high-quality filter material - Function: filter cartridge for standard suction cup filter units - Compatibility: fits standard suction cup filter units (no additional locking required) - Size: standard cartridge size - Performance: improves air supply, purifies recirculation, protects the engine Use scenarios - In passenger cars during routine maintenance to protect the engine and maintain efficient air recirculation. - In small engines such as motorcycles, ATVs, and lawn equipment used in dusty environments to preserve air quality and reduce engine strain. - In work vehicles or machinery at construction sites or farms where heavy dust is present to maintain exhaust air filtration and engine protection.
