Note: exhaust manifold studs are not included but can be ordered separately. We've removed many S55 turbos and only replaced a few studs so buying a whole set of studs seems unnecessary. It might be a good idea to order 2-3 to have just in case. Use blue threadlocker when installing a new stud.
BMW says to replace the hex bolts holding the undertray / reinforcement to the frame - BMW part #33326768354. These can be ordered separately from the Related Items list below.
To complete the job, we recommend ordering an oil change and coolant to replace fluid that is drained during the turbo replacement procedure. See below for BimmerWorld Recommended Related Items.
