VAC offers High Performance Valve Guides for all BMW models (both Standard and Oversized ODs).
These M10 / M30 guides are born from superior metallurgy than the original valve guides and offer improved wear characteristics under the stresses of high performance use.
They also work great as stock replacements and are built to last.
*Please be sure to check the valve guide bores in the cylinder head prior to ordering oversized guides and include it in the box above.
