Spark plug Autolite or AC DELCO

These are good plugs Autolite my mechanic recommended them to me good spark and seems like my truck is running smoothly and there a good price.

I am running platinum Autolite plugs in my 2.3 rwd and don't regret it

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.

I use them. Just replaced a set after they'd lasted 90,000 miles, only to rule out a very very tiny misfire count issue I've noticed lately. I might get a coil pack now, but those original plugs surely would have lasted longer (they say they should last for 100k).

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.

Standard replacement CR43TS Delco plugs, and a decent brand of wires. Bosch makes nice wires. Our engines don't exactly tax the ignition system, so if it's functional, you don't stand to gain much.

I wouldn't use Autolite in a Hyundai.

Not saying the auto lite won't work, but you're definitely not going to get 70k out of them.

That auto lite is no goood

Make sure if you purchase spark plugs that it is not Auto Light. They tend to mess your vehicle up more and not work well with Toyotas.
