I am running platinum Autolite plugs in my 2.3 rwd and don't regret it
Champion iridium. Champion makes the Mopar plugs. It's the closest thing to the original plugs without having to spend $30/plug.
In my 206 classes we run this autolite sparkplug because it’s required.
My understanding is that we switched because people were buying plugs in bulk and looking for ones with the lowest internal resistance believing it would effectively advance the engines timing. Supposedly these autolite plugs are much more consistent.
If you care more about performance, or cheaper cost, get the autolite a103, or ar103. Those will give you the best performance, but they only last like 10k. But they’re also dirt cheap.
I have measured resistance above 5k and determined the plug to be causing a problem. Typical resistance is 1-3 kOhm, sometimes less for a new one.
Autolite are pure trash maybe suitable for a lawn mower if you like breaking plugs off in heads
Champion are the only plugs I’ve had the ceramic crack on, so no more Champion for me.
My service center guys installed Champion plug instead of Bosch on my turbocharged Altroz. Company user manual clearly says to use Bosch in TC. My car's economy has dropped significantly...and I'm just frustrated.
I won't run champion plugs in anything but lawn mowers. That's the only thing I've put them in that didn't get angry about it. Guess everybody's vehicles are different, but personally I don't think they're very good plugs.
Autolites gotta be the worst fkn plugs on the market rn.
