Standard dimension tri-metal conrod bearing shells for BMWE30 M3

Set of standard dimension conrod bearing shells for E30 M3 2.0, 2.3and 2.5 S14B20, S14B23 and S14B25 engines Designed to withstand high temperatures and stress levels, these high-resistance bearing shells are made from3 thicknesses of tempered steel, copper and nickel.
This so-called "tri-metal" composition clearly reduces friction, thus reducing running temperatures whilst assuring greater lubrication than before.
