In the honda world they are frowned upon....and proven to be no better, infact there is more shrouding of the spark, and there has been cases where one of the 4 tips came off causing engine failure.

Sounds great on paper, but in practice it doesn't live up to the claims.

But give them a try, just because it doesn't work for Honda tuners doesn't mean it won't work on the Benzes.
