Product Description
This is a direct replacement of the seal found on the Disa valve ( intake adjuster ) housing for M54 and M52TU engines.
It's made out of high quality viton material rather than the cheaper Buna material used by BMW, so it is good to last the lifetime of the engine.
We advise replacing the seals to avoid any air leaks, esepcially if the Disa unit has been removed from the engine multiple times.
Internal Diameter 52.07MM
External Diameter 58.00MM
Cross Section 2.62mm
