Product Details
This set includes Mahle OE Piston Rings, specifically the THM-13 model. These rings are constructed from steel and feature a Napier hook design, which is known for its effectiveness in controlling oil consumption. The dimensions are 4.155 inches bore size, with ring thicknesses of 1.5mm for the top and second rings, and a 0.150-inch ring width for the oil control ring.
The Napier hook design on the second ring helps to scrape oil from the cylinder wall more efficiently, preventing it from entering the combustion chamber. This can lead to reduced oil burning and a cleaner exhaust. Steel construction offers good durability for performance applications.
