As mentioned in the E-type forum, here is my first hand experience with Bosch plugs. The ground electrodes do fall off. Lots of internet mention of this, and no responce when trying to contact Bosch about it. If you don't like the thought of a ground electrode riding up & down in your engine for a while I'd stay with other brands.

Supposedly premium range plugs and they look in a very bad way. What kind of mileage on these?

About half the expected life. Not surprising Bosch are keeping quiet.

The Bosch oil filters for the AJ27 aren't too impressive either. It is shorter than the OEM. Presumably this is in the interest of part number rationalisation.

 

Wow... Disappointing to see.

But then, it is also sad to see Bosch following the "multi-electrode" marketing ploy.

Is this happening on any of Bosch normal plugs?
