Product Details

The MAHLE 9250MS-12 is a high-performance piston ring set designed for 92.50mm bore applications with ring widths of 1.2mm, 1.2mm, and 2.8mm. These rings are engineered for piston SUB193642I16 and deliver reduced friction for measurable horsepower gains.

Advanced Ring Design:

  • Top compression rings feature ductile iron construction with plasma-moly barrel face coating for superior wear resistance and sealing
  • Second compression ring uses cast iron reverse twist design to optimize cylinder wall contact and oil control
  • Three-piece oil ring assembly provides excellent oil control and reduced friction
  • Ultra-flat ring flanks maximize ring-to-piston sealing interface

Performance Benefits:

  • Minimized friction delivers "free" horsepower without engine modifications
  • Computer-optimized ring profiles developed through advanced simulation technology
  • Drop-in installation for coordinated MAHLE piston assemblies
  • Proven performance on both dynamometer testing and competitive racing applications

MAHLE piston rings are precision-manufactured to exceed high-performance requirements, making them the choice of engine builders and racers worldwide.

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

Excellent experience. Shipped when they said it would ship. Very good web site to navigate through.<br>Thank you, Autoplicity

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

Best prices I can find!

Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.
