Bosch YR6LDE Spark Plug

Bosch YR6LDE Nickel Spark Plug Overview

The Bosch YR6LDE is a conventional nickel-copper spark plug built for steady ignition performance and OE-style value. It uses a yttrium-enhanced nickel center electrode with a copper core to support longer service life than a basic copper-core design, while maintaining the ignition characteristics expected in secondary ignition service.

Compatible With BMW Z4 2006-2008, BMW M3 2001-2006, and BMW Z3 2001-2002, this Bosch Nickel spark plug is a direct-fit option for drivers servicing factory-style ignition systems. The YR6LDE part number is also useful when matching the correct heat range and reach for these applications.
