I've used Autolite plugs in the 2.0's I've owned for over 20 years now because I think they work the best of the ones I've tried with this engine.
Pros: work the best, long-term use
Vehicle:
Volkswagen Jetta
Just swapped all four plugs in my 2013 Kia optima EX 2.4l for ngk iridium’s, still had the original sensor plugs in at 91k so honestly not sure how I didn’t have any misfires but have had a rough idle
Pros: fixed rough idle
Cons: plugs looked cooked
Vehicle:
Kia Optima
Mileage: 91000 km
Using the muzzler has stopped mine needing the spark plugs changed / having a cylinder go out every 6 weeks.
Pros: stopped needing spark plugs changed
Cons: cylinder goes out
Vehicle:

I put a new battery in it. Because it needed one but then I changed the spark blood wires and it now acts like a brand new car, so go to your spark plugs first.
Pros: acts like new car
Vehicle:
Volkswagen Jetta
Heat Exchanger, also Brisk racing spark plugs I gapped mine to 0.026”.

So, I changed spark plugs in an old Ford Focus 2001. And currently there's no way I can get the original Motocraft spark plugs, so I bought and installed the NGK ones which are supposedly compatible with my vehicle. I used them a week, but since the start I noticed great differences in size in the threads and in the shape of the head. Is this a problem?
Cons: size differences, shape differences
Vehicle:
Ford Focus
Mann fuel and air filter, Bosch distributor cap and rotor, NGK spark plugs and NGK wires. I had Bosch spark plugs W6DPO, the car runs exactly the same.
Cons: car runs the same
Part number: W6DPO
I tried Bosch plugs on a 1995 NG900. Problem as described. When they state compatible, that might only address mechanical fit. Stick with the original plugs
Cons: problem as described
Vehicle:
Saab
