My 92 500 SL book calls for a Bosch F8 DC0 plug gapped at 32. Dealer sold me F8 DC4 plugs and said gap should be 40. Can someone please verify this, thanks.
If you were running on unleaded fuel, then I believe the higher gap would be in order.<br> <br> Also with unleaded fuel, the plug change out interval, increases to 24,000 miles.<br> <br> Regards<br> <br> Col<br>
