MAHLE Air Filter LX1781/2. This premium filter is designed to meet OE quality standards and is manufactured by Mahle, a world-leading supplier of filters. It effectively captures up to 99.98% of toxic dust, soot, and tyre particles, ensuring durability and maximizing fuel efficiency. The filter material is impregnated with a special synthetic resin for increased resistance to water and chemicals, and glue beads on the folds help maintain the filter's shape. This prevents premature wear of critical engine components such as valves, cylinder surfaces, piston rings, and bearings. Replace the filter at the intervals prescribed by the vehicle manufacturer. Dimensions are 268mm length x 147mm width x 42mm height. Compatible with BMW and Rolls-Royce models including the Rolls-Royce Ghost and Phantom 6.75 (2017 onwards).
