Spark plug Bosch or BRISK

I've had my Bosch platinum spark plugs in for 120k+ kilometers and they still run as good as they did the day I installed them, back in 2011.

the original spark plugs died (delphi) so i changed them for Bosch ones

We used to put Bosch W7DTC spark plugs in them. No gapping required, smoother idle, and they last 60k miles, maybe more.

You can get NGK or Bosch plugs on rockauto for around $10. Not sure which was OEM, some like NGK for Mercedes in general but Bosch tends to be the OEM maker of plugs for MB.

I recently changed my spark plugs on 2012 Ford Focus. I used Bosch and got a 3 MPG boost.

I have used Rs7 plugs (meh), the APR recommended NGK plugs (rough idle, gapped correctly), and the Brisk ER12S. I'm on my second set of the Brisk, and plan to keep using them.

would suggest plugs, RS7 or Brisk 12's (cheaper) but coil packs are not needed.

I've heard for many decades how bad Bosch spark plugs are and I figured the coils would be just as bad, if not worse.

Bosch spark plugs are junk.

This is why I don't use Bosch plugs. It goes back to the quad fire plugs with a platinum center electrode that would fall out.
