2007 550i 62,000 miles on Odometer, I want to replace them because I am the second owner and want to be safe. Just wanted to know who uses what as a spark plug replacement. I want something that is pre-spaced to OEM specs and will meet or exceed OEM standards. I know everyone has there favorites but I would like YOUR pick and a quick explanation why. Any and all suggestions will be greatly appreciated!

OEM, why? because it's just a spark plug.

Pre-spaced to OEM specs, after that its all gravy.

Bosch platinum +4. They are OEM 5 yr warranty and cost $5 each at Autozone.

either the bosch +4 or the NGKs. My car had NGKs when I swapped them out at 60k. I went with Bosch Iridium fusions. mileage went up but that's expected when replacing 60k old plugs.

I just got Bosch Platinum Iridium Fusion installed last month, they have been legit! They were around $7-8 each on Amazon.

OP - Again, either Bosch or NGK +4 are the OEM. You will find either depending on the car. Since they do offer 5 yr replacement if defective you will spend $5 each and just replace them every 30,000 miles free of charge. Why not? It takes 15 min, is super easy and you'll have a piece of mind....especially when you aren't paying for the new ones.
