MAHLE 224-3549-0.10MM Engine Piston Set — 3.390 in. Bore, +0.10mm Oversize

The MAHLE 224-3549-0.10MM is an OE-quality replacement engine piston set featuring a 3.390-inch bore diameter in a +0.10mm oversize specification, precision-machined to tight tolerances for reliable performance and long service life.

MAHLE is one of the largest original equipment piston manufacturers in the world, and this aftermarket replacement piston set is engineered to the same demanding standards as factory components. Each piston is designed with compensated ring grooves to ensure proper ring loading and oil control, along with expansion-controlled designs for tight fitting clearances that reduce engine noise, wear, and emissions while improving oil control.

Key Features:

• OE form, fit, and function — precision machined to factory specifications for a direct replacement fit
• Compensated ring grooves — assure proper ring loading and consistent oil control
• Expansion-controlled design — minimizes fitting clearances to reduce noise, wear, and emissions
• Lightweight construction — reduces reciprocating mass to lower bearing loads and improve engine response
• MAHLE GRAFAL® anti-friction skirt coating (on applicable models) — graphite-impregnated resin reduces drag, scuffing, and cylinder bore wear
• 3.390 in. bore diameter — +0.10mm oversize for use in engines that have been bored to oversize specification

Note: Piston rings are not included with this set. Pin and clips are included for the convenience of the engine builder. Sold as a set.

Backed by decades of OE manufacturing expertise, MAHLE replacement pistons are the trusted choice for professional engine builders and rebuilders seeking factory-level quality in an aftermarket part.
