The MAHLE KL 15 is a premium in-line fuel filter designed to capture microscopic contaminants and debris. Measuring 143.5 mm in height with a 30 mm diameter, it features a 6 mm inlet and a 6.1 mm outlet. It is built with a durable stainless steel outer casing and advanced embossed filter media.

Designed primarily for classic passenger cars and off-road vehicles—including vintage Audi, Volkswagen, Ford, Gas Gas and KTM models—it helps prevent engine hesitation, fuel pump failure, and poor performance caused by dirt or moisture.
