Detailed Application and Function

URO part number 11127835170 is a spark plug tube for BMW secondary ignition service. In applications such as the BMW M3, M5, and M6, a worn tube can allow oil to collect around the spark plug well, which can lead to misfire symptoms and degraded engine performance. This OE-style replacement is shaped to maintain the correct seal between the valve cover and head, supporting proper ignition system operation.

This part cross-references URO-011191 for the same application.

What It Helps Address

• Oil accumulation around the spark plug
