Porsche Fuel Filter - Mahle KL21

Product Information

It is important to keep all dirt and foreign matter out of your fuel system to ensure its optimum performance. A clogged fuel filter can reduce engine performance as well as increase the load on the fuel pump which can potentially burn out its motor. It can be difficult to know when the fuel filter needs to be changed, so we suggest changing your fuel filter at your car manufacturer's suggested intervals, which is often during a tune up.

• Low Fuel Pressure
• Poor Engine Performance
• Hesitation on Acceleration
• Failed Fuel Pump

About Mahle

Mahle began in 1920 when pistons made of heavy gray cast iron were being used in internal combustion engines for automobiles and there was a need for a new design. The Mahle brothers countered this trend by producing light-alloy pistons at their small, newly established company however the technology was still finicky and problems come up frequently. They soon determined that they needed to come up with a solution to keep dirt and dust out of the engine so they eventually developed air and oil filters as well. Their perseverance paid off and the light-alloy pistons began to take over the market. Today, half of all automobiles produced worldwide contain MAHLE components. MAHLE offers an extensive range of parts for everyone including pistons, cylinder liners, piston ring sets, bearings, assemblies, valves, valve train components, and air, oil, fuel, and cabin air filters. Their catalog and online database of aftermarket engine components is an indispensable reference.
