For 98K miles, the COPs look almost new when looking at the sides and tops. I'm wondering if they have already been replaced. Also takes very little to crank the engine. Best price I have found for new DG511s is WaL Mart at about 28 bucks each. Their photo shows a COP with a black top and numbers, with a blue dot. COPs on the engine have black tops and numbers with no blue dot. Does that sound like the original COPs, or have they been replaced? Thanks in advance.

 

If the numbers are in the Ford part number format (3L3Z12029BA), they are probably original.

 

Thanks.
