Porsche Piston Ring Set - Mahle 93010396800

Product Information

An engine piston ring set consists of multiple rings that fit into grooves around each piston. Their main roles are to seal the combustion chamber, regulate oil consumption by scraping excess oil from cylinder walls, and transfer heat from the piston to the cylinder wall. Typically, a set includes compression rings (for sealing combustion gases) and oil control rings (for managing lubrication).

• Excessive exhaust smoke (blue or gray), caused by oil leaking into the combustion chamber.
• Loss of compression and power, leading to poor acceleration and misfires.
• High oil consumption, requiring frequent top-ups due to oil burning inside the cylinders.

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.
