Yes, the BKR6EQUP are OEM along with Bosch FGR7DQP that I pulled out. People prefer one or other but I never had an issue with these NGK's.
I did about 50 miles today and I believe truck is running slightly better but probably due to fresh plugs vs. tired ones.
I got 14 mpg with mix highway and city but I don't care. The beast rules the road. I'm use to my 540 holding its own on the road but the X5 is quickly becoming my favorite. I can't believe I'm saying this as I always prefer 6 speed and better handling.
Now the air and fuel filter along with PS reservoir hose (the parts are coming tomorrow) and she's up to date on maintenance and repairs.
