BACKGROUND
The Table lists possible third-party suppliers of air filters for the INEOS Grenadier B57 Diesel Motor (the air filter is also used on the B58 NEEDS CONFRIMATION).
When in doubt use the INEOS air filter. The INEOS filter is 68mm thick. The 68mm includes the rubber/silicone seal on the top of the filter. Some other BMW air filters are the same shape but a different thickness.
