IATF-16949 Certified

-C.T.I. has over 12,000 engine references for piston rings.

● Especially BLACK DIAMOND piston ring has the advantage of high hardness, low friction coefficient and high wear resistance, and by reducing wear rate and decreasing internal stress extend the life of piston rings.

● BLACK DIAMOND piston ring also contributes to lower fuel consumption by 10%, and to reduce carbon emission simultaneously, which is not only energy-saving but also eco-friendly.
