Mahle 9200MS-12 Piston Ring Set, 92.00mm Bore, 1.2/1.2/2.8mm Drop-In

Compatible Applications

• Universal - for engine builds using a 92.00mm bore piston, common on many sport compact 4-cylinder applications

Fitment Notes

• 92.00mm bore diameter
• 1.2mm top ring / 1.2mm second ring / 2.8mm oil ring, drop-in fit
• Confirm your exact piston bore and ring groove specifications match before ordering

Features

• Mahle pioneered the use of piston ring simulation and computer development tools to design rings that minimize friction and free up usable horsepower
• Performance gains are measurable on both the dyno and the track versus standard replacement rings
• Ultra-flat ring flanks maximize ring-to-piston sealing for consistent cylinder pressure and reduced blow-by
• Top ring: ductile iron, plasma moly, barrel-face configuration for excellent wear resistance and sealing
• Second ring: cast iron, reverse-twist design for improved oil control and reduced ring flutter at high RPM
• 3-piece oil ring design, available in both standard and low-tension configurations for reduced parasitic friction

Product Description

The Mahle 9200MS-12 piston ring set brings computer-simulated ring design to 92.00mm bore sport compact engine builds, using Mahle's pioneering friction-minimizing technology to free up real horsepower - a difference that shows up on both the dyno and the track. The set's ultra-flat ring flanks maximize sealing between the ring and piston, supporting consistent cylinder pressure and reduced blow-by across the RPM range.

The plasma-moly ductile iron top ring and reverse-twist cast iron second ring are engineered for durability and improved oil control, while the 3-piece oil ring - available in standard or low-tension form - helps minimize parasitic friction losses. For engine builders working with a 92.00mm bore and looking for genuine ring-to-piston sealing performance, this set is a proven, application-specific upgrade over generic replacement rings.
