The factory produced these parts in
plastic, which is good for a few years. But eventually, the
flexibility fades and the plastic becomes brittle. This means this
part will crack and break - often leaving you stuck.
Replace the factory piece with these
quality aluminum replacements! These parts are available US M50
based engines (92-99 3 Series, 5 Series, and Z3 with 6 cylinder
engine, including M models) and V8 models 92-95. Gasket included if
required.
