The MAHLE S42139 is a precision-engineered piston ring set designed to restore proper cylinder sealing, compression, and oil control in your engine. MAHLE is a globally recognized OEM and aftermarket supplier trusted by major automotive manufacturers for piston rings and engine components.

Key Features:

  • Manufactured to OEM specifications for precise fit and reliable sealing performance
  • Engineered to restore engine compression and reduce oil consumption
  • High-quality materials resist wear, heat, and thermal cycling for extended service life
  • Surface coatings and treatments help reduce break-in time and improve ring seating

MAHLE piston rings undergo rigorous quality control processes, reflecting the brand's deep experience as a Tier 1 OEM supplier. Replacing worn piston rings with a quality set like the S42139 helps recover lost compression, reduce blow-by, and improve overall engine efficiency. Always verify the correct ring gap during installation per engine manufacturer specifications.

I REALLY NEEDED THE PARTS ORDERED AND ORDERING WAS EASY, BUT I FOUND WHAT I NEEDED AND CANCELED THE ORDER...

Good communication, very slow shipping. Placed my order on 3/8/12 it didn't even ship until 3/20/12. Then another 4 to 5 days after that for it to arrive.
