MAHLE 224-3448WR OE Replacement Engine Piston Set with Rings

The MAHLE 224-3448WR is a complete OE-replacement engine piston set, supplied with piston rings pre-mounted and ready for installation. As one of the world's largest original equipment piston manufacturers, MAHLE engineers these pistons to the same exacting standards used in factory production — delivering a precise fit and reliable, long-term performance.

Key Features:

• Compensated ring grooves ensure proper ring loading and consistent oil control throughout the piston's service life
• Expansion-controlled design provides tight fitting clearances that minimize engine noise, reduce wear, lower emissions, and improve oil consumption
• MAHLE GRAFAL® anti-friction skirt coating (graphite-impregnated resin) reduces drag, scuffing, friction, and cylinder bore wear
• Precision-machined to tight tolerances for OE form, fit, and function — no additional machining required
• Lightweight construction reduces reciprocating mass, lowering bearing loads and improving engine response
• Complete kit — rings are pre-installed; wrist pin and clips included for engine builder convenience

MAHLE Original replacement pistons are a trusted choice for professional engine builders and rebuilders. The "WR" designation confirms that piston rings are pre-mounted on each piston, streamlining assembly and reducing the chance of installation errors. Each set is balanced to OE specifications for smooth, quiet engine operation.
