What kind of spark plugs are in a 2013 Ford Fiesta?
The OEM spark plugs in this 2013 Ford Fiesta hatchback with the Duratec 1.6L I4 engine were part number CYFS12YEC. I recommend buying the Denso (5339) ITV20 iridium tipped spark plugs since they have great reviews on Amazon specifically for Ford vehicles.
Do you need to set the spark plug gap?
Spark Plug Gap setting is important for proper engine operation. To set the spark plug gap correctly, you need to use a spark plug gap tool. For reference, see our spark plug gap chart below, this chart converts metric measurements to standard.
Why are spark plugs so hard to fire?
Used spark plugs are hard to fire as the gaps are worn out, and insulation properties of the ceramic is compromised by solid combustion deposits and old fuel saturation. This robs available voltage at the spark plug gap, as it “leaks” through the low resistance carbon deposits to the ground, resulting in a weak spark.

The gap is the distance between the center and side electrodes, set so arcing occurs at the proper voltage that ignites the fuel and generates the combustion that makes the engine run.

What should the spark plug gap be on a Ford Ranger?
So I have a 2000 Ford Ranger XLT 4.0L V6 OHV Engine and I recently replaced the spark plugs. The thing is, the original recommended spark plugs have a gap of 0.52-0.56, which is what is recommended in the Haynes manual. However, I think some time between 2000 and now, the recommended plugs changed to another model, which is factory gapped to 0.44.
What’s the best way to adjust a spark plug?
Use your spark plug gap tool to adjust the gap. Gently bend the ground electrode in to narrow the gap or bend it out to widen it. Be very careful when making adjustments. Don’t bend the electrode more than a few fractions of an inch. It is durable but isn’t designed to take a lot of pressure. Also, take care not to hit the center electrode.
