Diffuser BMW E46 saloon coupé touring M Sport package

Installation and delivery

Because of its size and the risk of damage in transit, the BMW E46 diffuser is shipped in parts. You assemble it yourself with the supplied parts. First choose which of the two variants you want, lay out all the parts and fit them together loosely before you tighten everything.

Then hold the BMW E46 diffuser against the bumper to determine its position. Work neatly, check the ground clearance and make sure nothing touches the exhaust. On a heavily lowered car, it is wise to check everything again after the first few drives.

You will find more aero parts for the rear in our diffusers category.
