01 1.3 Spark plug choice - andyj941
Hi I bought some spark plugs for the fiesta the other day from halfords using their ref guide. They are champion EON3 (703). I've measured the gap using feeler blades and reckon it's about 0.95mm (although it's very tight when pushing the blades in). However the user manual and spark-plugs.co.uk say it should be 1.0mm and RS9PYP4 OE131 champion spark plugs. Why is there a difference and what should I do? What is the difference between these two types?

No idea of the difference, but www.spark-plugs.co.uk suggest they should be RS9PYP4 OE131 and gapped to 1.0 mm as well.

Put them in as they are.The gap is within limits-Ford quote +/-0.05.And they will gradually wear bigger.
