I always get the manufacturer's recommend brand for my cars, but for my Lincoln I'm using iridium because they're not that much more expensive, and the gap is larger than your typical vehicle for the era, paired with decent coils. Hopefully be enough to keep it running like new for the next 100k miles.

OEM for whatever car. Setting the gap to manufacturer's specs and keeping them clean is the more important thing.

Just use what a manufacturer of the car told you to use, no matter what shop owners tell you. These are the best for your car. If you tune your car strongly, then use colder plugs from the same brand line.

I prefer the ngk v version. A cheap yet reliable (thick electrode won't wear easily) and slightly better (v gap allow more spark-fuel contact) than the regular.

I use $2.40 champion spark plugs in my hog and always do fine!

Unless you’re racing your car there is no reason to pay for high end plugs. Just get what the manufacturer recommends.

If you have an Aluminum head always buy spark plugs with nickel plated threads. If you don't the aluminum threads in the head will stick to the steel spark plug threads and you'll end up with stripped out spark plugs holes in your head, which is difficult to fix properly without removing the head. In my youth I fixed hundreds of stripped out spark plug holes in air cooled VW head's because people would use cheap Champion spark plugs, which always ruined VW head's.
