NOTE: These bearings are now sold as SP1534F which features a new and improved silver oxide coating that is stronger and more durable! Designed and manufactured by Clevite to BE Bearing specifications. These bearings replace the factory BMW rod bearings. The original BMW bearings have too little clearance, which leads to premature bearing wear and can cause early engine failure. Furthermore, the factory BMW bearings are made from tin-aluminum which are 5-times harder than a softer lead-copper bearing design. A softer bearing is better for your engine and more tolerant of foreign particles suspended in your oil. These BE Bearings feature a state-of-the-art Clevite Tri-Metal design with the Clevite Tri-Armor(tm) coating. Lead-copper design for greater durability and easy tracking with oil analysis like Blackstone (recommended). Designed with extra clearance to "fix" the BMW rod bearing design flaw. Designed for use with factory 10W60 weight oils. Tri-Armor coated for low conditions during cold start Ideal for start-stop vehicles Applicable for BMW engines S54 Standard size Sold as complete set (6-cylinders) Fits the following BMWs: 2002-2006 E46 BMW M3 S54 2002-2003 Z3 BMW M Coupe, M Roadster S54 2006-2008 Z4 BMW M Coupe, M Roadster S54
