Product Details

The MAHLE 3020142 is a precision-ground performance piston ring set engineered to OEM and high-performance standards. MAHLE is a globally recognized leader in engine component manufacturing, supplying rings to major OEMs and the performance aftermarket alike. These rings are designed to deliver reliable sealing, reduced blowby, and optimized oil control for demanding engine applications.

Key Features:

  • Precision-ground profiles for consistent ring-to-bore sealing and reduced break-in time
  • High-strength materials — MAHLE performance rings typically utilize ductile iron or steel construction with advanced surface treatments (such as PVD or gas-nitrided coatings) for enhanced wear resistance
  • Multi-piece ring set — includes compression rings and oil control ring assembly as required for a complete piston ring installation
  • Tight dimensional tolerances to ensure proper end gap and side clearance for optimal performance
  • Compatible with both naturally aspirated and forced-induction applications where specified

MAHLE piston rings undergo rigorous quality control processes, meeting or exceeding OEM specifications. Whether used in a rebuild or a high-performance build, the MAHLE 3020142 ring set provides the durability and sealing integrity required for long engine life and consistent power output.

as of the moment, the shopping process has been great

Quick and easy shopping.

Great prices. Cheaper by quite a bit over Summit.

Easy website, fast service. Shipping cost seems high. thank you

This was my first purchase from Autoplicity, and it was an excellent experience. They had the Motive brake bleeder adapter I needed at the best price I could find on the web. Shipping was prompt and the transaction was super smooth. Thanks!

Rather amazing and uneventful service in this day and age. Ordered a Thule bike rack for my Nissan Murano. It was in stock (unusual for high-end specialty products), shipped the next day, and was on my doorstep in a few days (excellent for a 60 lb. large box). I'd buy anything from these people without any reservation. AND, your order is insured - completely superfluous. Oh, and did I mention, the lowest price I could find ANYWHERE, and not by a few dollars - a lot.

Great prices
