Mahle Air Filter Insert (LX4239)

Clean air intake is one of the most important conditions for optimal engine power, high torque, low fuel consumption and minimized pollutant emissions. With MAHLE air filters, up to 99.9 percent of dust, soot and tire wear particles are filtered out. At the same time, an optimal air/fuel mixture is assured. The high particle uptake capacity ensures long service life under extreme conditions such as heat, cold or chemical contaminants. Their quality filters prevent premature wear of valves, cylinder working surfaces, piston rings, bearings and other engine components. To ensure optimum filter performance, all filters should be replaced within the service intervals stipulated by the car manufacturers.
