Reviews of OEM BMW fuel injector

I actually just traded in my 2020 750i xDrive after 3 years of ownership...Had 2 fuel injectors go bad, suspension arm issues, a battery needing replacing and misc other repairs totaling 10k.

I got stung having to replace all of mine and coding them all.

So far I have replaced an injector on cilinder 3 (which has/had missfires). This helped a bit but not everything, still white smoke and a little rough when cold.

For my E30 325i, the biggest performance I gained from cleaning the injectors. When I bought the car I drove it 2000 miles around Europe and noticed sluggish drive in speeds under 100km/h.

Pulled the injectors out and it had what looked like decade full of gunk. Spray pattern non existing. Just weeped fuel through the gunk. Gave them ultrasonic bath and rebuilt them. Car now feels very responsive in city driving and accelerates nicely in highways.
