I just picked up some new spark plugs for my 1989 300E. I got them from my mercedes mechanic who I have known for several years and who has thus far proved trustworthy and professional.

I have always used Bosch Super plugs, but he sold me Beru Ultra plugs this time.

Does anyone have any experience with this brand? I have never heard of them and am reluctant to use them. (I'm also wondering if my mechanic got a good deal on a bulk shipment of these...). They are made in France. He also mentioned that many of the Bosch plugs are now made in India and lack their original quality.

Opinions?
