Very tight fit
Part fits ok, very tight fit on the throttle body side, you have to push very hard to get the c-clip to lock.

Did not fit, had air leaks
Waste of money, would not seal correctly, continued to set off engine warning light, had to replace with OEM BMW part to get the turbo to operate correctly, car ran horrible for several months until I removed this part and threw it away, don’t waste your money,

Great Alternative for an Amazing Price
I needed a new turbo pipe once mine went out on my 2015 535i.OEM was north of $400 while this was only $60. Only downside was that I had to wait 3 days for delivery but totally worth it.Mechanic said fitting was perfect just like OEM
