Wich spark plugs for 450SL '72 ?

My garagist changed my plugs ( it were plugs with 2 electrodes) and I feel less power and higher consumption.

Wich plugs should I use to gain power? With 2 or more electrodes??

Thank you for giving me all details.

All of the older MB's like yours should use Bosch W7DC OR W8DC plugs, both are single electrode plugs. Make sure they didn't install silver OR platinum electrode plugs.
