Engine Sealing Details

Victor Reinz focuses on sealing technology for engine components exposed to heat, oil, and vibration. This spark plug tube seal is intended for applications where maintaining a clean, secure seal around the valve cover area matters, especially on BMW M3, BMW M5, and BMW M6 engines from the listed model years. The 0.0790 thickness supports a precise sealing interface, while the flat rim shape helps the seal sit evenly during service. If you are replacing a worn seal on a BMW M5, BMW M3, or BMW M6, 71-27163-10 is a direct reference for the correct application.

This part cross-references BMW OE numbers 1 304 329 and 11 12 1 304 329 for the same application.
