So i have a 120d from 2007 m47 163hp and i want to delete the swirl flaps. Ive seen there is two sizes (22mm, 33mm) what should i choose?

Hi, I done the same, As far as I could make out its impossible to know what size you have without removing the manifold and checking so I just ordered both size kits on eBay as couldn't be bothered to take it off and re fit it twice , each kit is only about £12-£15. The cheap Chinese kits are just as good as the expensive ones. Before you take the manifold off its worth getting your codes read and make sure your glow plugs and regulator are working as these can only be accessed with the intake manifold removed so worth doing while its off.
