This is a genuine Mahle engine air filter insert, part number LX4298. It is designed for high quality and durability, meeting vehicle manufacturer standards to maximize fuel efficiency. The filter captures up to 99.98% of toxic dust, soot, and tire particles and has a high dust holding capacity. It is impregnated with a special synthetic resin that increases its resistance to water and chemicals. Glue beads on the backs of the folds help the filter elements retain their shape, preventing premature wear of engine components like valves, cylinder surfaces, piston rings, and bearings. The filter dimensions are 344mm in length, 145mm in width, and 42mm in height. It is compatible with MAZDA MX5 Mk4, ND 1.5 models from 2015 onwards, with OEM references including MAZDA P51N133A0A and PEES133A0.
