Product Details

The MAHLE Original 42149CP.030 is a premium plasma-moly piston ring set machined to a +0.030" oversize bore, designed for engine rebuilds requiring precise fitment in bored or worn cylinders. MAHLE is a global OE supplier whose piston rings are engineered to the same exacting standards as factory components, making them a top choice for professional engine builders and machine shops.

Key Features:

  • Pre-lapped finish — rings seat immediately upon installation, virtually eliminating traditional break-in time
  • Plasma-moly top compression ring (UCR) — barrel-faced contact profile with CNC-controlled gap chamfer for superior compression sealing and reduced blow-by
  • Intermediate ring (LCR) — reverse-twist design for enhanced groove side sealing, with taper-face machining to maximize cylinder wall contact
  • CP-20 oil control ring assembly (OCR) — exclusive 20-degree ear angle for optimal cylinder wall side sealing; chemically polished expander promotes efficient oil drain-back
  • Optimized ring tension — materials, coatings, and tension are application-specific to minimize friction and extend service life
  • OE-driven engineering — developed to meet original equipment requirements, reducing ring mass and oil consumption while maximizing durability
  • +0.030" oversize — engineered for cylinders bored 0.030" over standard diameter

MAHLE Original piston ring sets deliver the precision fit and long-term reliability demanded by today's engine rebuilding professionals. MPN: 42149CP.030

I had never heard of Autoplicity until I started shopping for an exhaust. I didn't think I was going to find the one I wanted at a decent price. Not only did they have my exhaust at a screaming deal, they had it to my door in perfect shape in 6 days including the evening of purchase and a weekend. I'll definitely look at buying from them again.

very easy to use

straight to the point.

Good website

Best price I've seen online and the shipping is extremely fast. I would definitely use this site again for future automobile needs.

So far so good, Autoplicity had what I wanted at a reasonable price, in stock and shipped within a day or so of order placement. I would ordere again, if I needed to do so.

I placed an order with autoplicity on Saturday order number 10468 I got it today and installed my new banks ram air box and it is awesome. Thanks autoplicity my box from Banks looks like it just came off the shelf even after ups delivered it.

Good so far

Good job

Autoplicity had the lowest price on what I ordered. Autoplicity was $30 cheaper than other competitors. I will return to Autoplicity again

Easy to order

Awesome price on this product. First time customer with you guys, but I will definitely be coming back if you keep your prices this aggressive!
