I'm looking for an alternative to the spark plugs that the Ford garage
normally mounts on my Fiesta 1.3, bought in 1994.
I'm specially interested in something slightly hotter than the
recommend spark plug - I do a lot of short journeys.
So far, I've able to find on the net the following alternatives to the
Motorcraft "original" part:
1) NGK BPR6EF or BPR6EFS (can anyone tell the diference between these
2?) What does the S stand for?). Supposed to provide the same
temperature level as original.
2) Bosch Super 4 FR 78 - supposed to provide a slightly higher
I've tried to find a BPR5EF(S), but apparently that is not
Any comments, or alternative suggestions, please?
