Product Description
Product Overview
This MLS (Multi-Layer Steel) engine intake manifold gasket (part number 11617530703) provides a precision-engineered airtight seal between the cylinder head and intake manifold in BMW engines. It prevents unmetered air leaks that can cause lean mixture conditions, maintains proper intake vacuum for brake booster operation, and protects against external contamination.
