NGK BCPR7ES i dont recall that heat range as standard with the vauxhall engine always had a 6 you could try a set of NGK BKR6E which is the iso of
BCPR6ES or BKR6EK which are the twin electrode version of BKR6E

Looks OK but the fact it is a very different from the others suggests looking a little deeper.
What fueling system are you using ? -- vacuum leak
Is the engine losing any water ? --- head gasket
How are the compression pressures ? --- exhaust valve not seating/burnt

If it is the same colour as the other 3 no problem
The plug has no signs of being overheated.
These days plug colour dosen't give as much info as it used to because of differences in fuel and the fact we all run weaker mixtures than
twenty years back.
