MAHLE 224-3862WR-0.25MM Engine Piston Set 0.25mm Oversize

The MAHLE 224-3862WR-0.25MM is a complete engine piston set manufactured to original equipment (OE) quality standards. MAHLE is one of the largest OE piston manufacturers in the world, supplying major automakers globally, and this set brings that same factory-level engineering to the replacement parts market.

Each piston features compensated ring grooves engineered to ensure proper ring loading and oil control throughout the life of the engine. The expansion-controlled design allows for tight fitting clearances, which directly reduces engine noise, minimizes wear, lowers emissions, and improves overall oil control.

Key Features:

• OE quality construction matching original manufacturer specifications
• Compensated ring grooves for consistent ring loading and oil control
• Expansion-controlled piston design for reduced fitting clearances
• Helps reduce engine noise, wear, and emissions
• 0.25mm oversize bore specification for engine rebuilds requiring minor oversizing
• Ready-to-install set includes mounted piston rings, wrist pin, and retaining clips
• Manufactured by one of the world's leading OE piston suppliers

This piston set is designed for engine builders seeking a convenient, complete assembly. With rings pre-mounted and the pin and clips included, installation is straightforward and efficient. The 0.25mm oversize dimension (also referenced as +0.010 in.) makes this set ideal for engines that have been bored to the first standard oversize during a rebuild.
