Need a spark club gap tool
These plugs are not pre-gapped. A few of them were significantly off what they needed to be, presumably due to damage during production.

Work great! Check their gap.
These were a perfect replacement in my 2014 Ford Fusion Hybrid. My car requires a gap of .051. These came out of the box varying from .040 to .045, so small adjustments were needed. Make sure you check yours when installing.

Pre-gapped
Always check and pretty much dead on .44 gap specs. Now to install which is easy and torque down to spec as well. Live OEM parts for a great price. Better than dealership prices.

I received the sparks (they were all open in the parcel) The mechanic installed them, Had an error on the dashboard. Replaced the Fire starter (Spark Coils) same issue. One of the spark plugs was faulty. Bad experience. Definitely wont buy again.
