Product Details

The MAHLE 8700MS-12 is a high-performance piston ring set engineered for 87.00mm bore applications, featuring ring thicknesses of 1.2mm, 1.2mm, and 2.8mm. This premium ring set is designed for Honda H22A engines, commonly found in performance Prelude builds, and is part of MAHLE's Golden Series lineup.

Key Features:

  • Ductile iron top ring with plasma-moly barrel face coating for superior wear resistance and heat dissipation
  • Cast iron second ring with reverse twist design to enhance oil control and sealing
  • 3-piece oil ring configuration for optimal cylinder wall lubrication
  • Ultra-flat ring flanks maximize ring-to-piston contact and sealing efficiency
  • Advanced ring simulation engineering reduces friction for measurable horsepower gains
  • Precision-manufactured to strict tolerances for consistent performance

MAHLE pioneered computer-aided piston ring development to minimize friction losses and unlock "free" horsepower. These rings are engineered to exceed high-performance demands on both the dyno and the track, making them an excellent choice for builders seeking reliable power gains and improved engine sealing in Honda H22A applications.

It was very good

Doesn't get much easier. Great prices!

Easy and fast

Vehicle data base needs some updating. Your online program says that these won't fit my car, but when I cross the Volvo OEM number it comes out to this Bilstein Part Number. I own a 2012 Volvo XC70 T6. Otherwise very easy to go through and order.

Nice job all around

good experence

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

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.

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