MAHLE 224-3523WR.020 Engine Piston Set Over - 020

The MAHLE 224-3523WR.020 is a complete engine piston set engineered to OE quality standards, offering a direct replacement solution for engine rebuilders and professional technicians. This is a .020" overbore piston set, designed for use during engine reconditioning where cylinder bores have been machined to the next oversize.

Key Features:

• OE-Quality Construction: Manufactured to the same specifications and tolerances as original equipment pistons, ensuring reliable performance and fit
• Compensated Ring Grooves: Precision-engineered ring grooves ensure proper ring loading and superior oil control throughout the piston's service life
• Expansion-Controlled Design: Tight fitting clearances minimize piston slap, reducing engine noise, wear, and emissions while improving oil control
• Ready-to-Install Kit: Each set includes mounted piston rings, wrist pin, and retaining clips for a complete, convenient installation package
• .020" Oversize: Sized for use with cylinders bored to .020" over standard diameter
• World-Class OE Manufacturer: MAHLE is one of the largest OE piston manufacturers in the world, supplying major automotive OEMs globally

MAHLE's expansion-controlled piston design reduces cold-start noise and wear by allowing minimal, precisely calculated clearance between the piston and cylinder wall. This technology helps lower exhaust emissions and extend engine service life — benefits that are equally valuable in a rebuilt engine as in a new one.

This piston set is ideal for engine builders performing professional overhaul work and includes all necessary hardware for installation, saving time and reducing the risk of missing components.
