Product Details

The MAHLE 4130MS-15 piston ring set is engineered for 4.125" bore engines with a .005" oversize tolerance. This file-fit ring set features standard tension design and utilizes MAHLE's advanced ring simulation technology to minimize friction and unlock free horsepower.

Ring Configuration:

  • Top Ring: 1.5mm ductile iron with plasma moly coating and barrel face profile for superior seal and wear resistance
  • Second Ring: 1.5mm cast iron with reverse twist design to enhance oil control and cylinder wall sealing
  • Oil Ring: 3.0mm 3-piece standard tension design for optimal oil management

Key Features:

  • File-fit design allows precision end-gap adjustment for custom engine builds
  • Ultra-flat ring flanks maximize ring-to-piston groove sealing
  • Plasma moly top ring coating provides exceptional durability under high heat and pressure
  • Computer-optimized ring design reduces parasitic friction losses
  • Standard tension configuration balances sealing performance with minimal friction

Super Fast! Website was easy to user, multiple different payment options (Amazon, Paypal, Credit Card) Got a notification of shipment within 1 hour!

Great service, awesome prices, incredibly fast shipping. A++ I would absolutely suggest you to my friends and family

quick response and unbelievably CHEAP prices.

Very easy shopping, and had hard to find parts.

Excellent service, quick ship. An easy transaction.

Ordered a set of 5 steel wheels, distributor messed up and only sent me 4. 5th wheel is taking a good couple weeks to arrive due to the distributor messing up the shipment. Autoplicity did make things right and I can honestly say now I would recommend them.

Easy site to use One great security issue the company actualy calls you to confirm the purchase to avove fraud. Excellent job!! i will buy from you again. Bill

- Updated review -<br>Autoplicity.com contacted me after my original review and admitted to making a mistake with my order. They have refunded my shipping and I am happy now.<br><br>- Original review -<br>After 18 days the part finally arrived. The filter appears to have been sent directly from K&N, but I ordered on the 20th of June, yet the packing date that K&N Engineering Inc. shows is July 3rd.

Very pleased with Autoplicity's fast and efficient service. The part I ordered fit and looked great. Will definitely consider Autoplicity for future orders. Thanks.
