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.

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.

Not good product, received faulty product
I ordered 6 spark plugs for my Malibu, and one of them was faulty. It proceeded to make my car misfire horribly and kill one of my coils in my engine costing 300 dollars to fix. Do yourself the favor and buy them in person, and save the money.

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.
