Fastlane spark plug question
 

Hi,
When I go to fastlane to buy sparkplugs for my 99ML320, I am faced with a dizzying array of choices - 4 different plugs.

Which ones should I be getting?

Thanks

I used the Bosch plugs sold by the dealer to make sure I got the correct ones. Just call a dealer and ask for the Bosch plug number. Sorry I don't remember the part number for the plugs I put in.

As an alternative you might consider doing a seach of this forum for the correct part number for the ML plug. I'm pretty sure I recall seeing someone posting the correct part number.

Sould be the Bosch plug at the top of the list. It's a "F 8 DPP332" that has replaced the original plug. I just replaced mine, works like a charm.

It doesn't make sense to pay extra to put Japanese plugs in a Mercedes. My dealer said stock is Bosch or Beru. When I was in he had the Berus so that's what I put in. I wonder why the platinum +4's are so much less than the other Bosch plugs on Fastlane? I don't think you'd go wrong with either choice.

You can use the new 4301 Bosch two electrode, works well. I would not bother with the four electrode, no difference in performance.
Auto Zone or others have them.
