Motorcraft Spark Plug - SP580X

Fits 2017 F150 3.5EB , wish they were better packaged though. The boxes were flattened and beat up but spark plugs work and fit great.

I'm driving a 2015 Ford Expedition and it started to misfire. Figured I first go the cheapest route by replacing the spark plugs since I had the last replacement about 44k miles ago. (Had exactly the same plugs last time, and yes I know they are only rated for 30k miles, but lasted almost 44k miles without issues)Got these and replaced the old ones and the misfire is gone. Perfect fit replacement plugs. Great value since they are quite a bit cheaper than buying at your local parts dealer. Already perfectly pre-gapped.Recommend if u want the Ford factory plugs and don't want to spend an arm and a leg.

These were a direct replacement for my 2013 3.5L Ecoboost engine with just over 100k miles on it. They say you should replace your plugs every 100k miles. Mine made it about 101k before I starting having a misfire. Pulled the plugs and 2 needed to be replaced. These dropped right in and it was up and running like new.

Check the gap! For whatever reason I had to slightly adjust every one of them. After that, perfect replacement.

These plugs work great on our 2013 Flex EB.
