I used the gimmicky Bosch Platinum 4+ plugs which solved that problem (no more CELs) but sometimes idle is still a bit rough.
I got a sp series cold air intake and ecs performance ignition coils with bosch spark plugs. I once ran this car with 3 spark plugs for to much time and almost no oil at one point too.
I couldn’t use any other spark plugs I had to use those or my car would run like crap.
In my 2012 with the 2.5L engine, I replaced my spark plugs with Bosch Iridium (#96302), around 90K miles. It's been great since.
I also put Motorcraft new plugs back in. Truck is happy. I'm happy.
I also added bosch sparkplugs 4 months ago, and also have some stuttering.
I don't say for 100% sure but my understanding is that Bosch and NGK are the ones you should use
I replaced mine with Bosch once, it drove like shit and I immediately replaced them with NGK.
I put the expensive double spark, spark plugs into a Mitsubishi galant one time. Plugs were supposed to be hotter and make the car run better, after a couple weeks I swapped them back out for nkg’s that I checked the gap on, car ran better.
Never use bosch plugs. I work in a bosch car service and we won't use em, NGK only. Bosch stuff is garbage
