Very dissapointed! by Keldawwg, September 8, 2011

Overall Rating:

Replacing plugs in my 400 E is something I don't look forward to, so I wanted to get really good plugs. These plugs did not fill that bill in the slightest. I put them in, and a couple of months later my wife reported that the car was not running great. I started looking for a problem, and went through the whole car. I actually replaced the throttle body, since everything else was new. (over $1000 part) It still ran poorly, stumbling at several rpm ranges. I finally pulled a plug, and it looked horrible! All of the ground electrodes were badly eroded. I put in a set of NGK Platinums, and it runs like a new car... I will never buy Bosch Platinum +4's again! Very expensive junk!
