Spark plug Autolite or BERU
I am running platinum Autolite plugs in my 2.3 rwd and don't regret it
Pros: don't regret it
use beru plugs rather than Bosch, a lot of Bosch plugs sold for this application has the wrong heat range which can cause misfires.
Pros: correct heat range
Cons: wrong heat range
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.
Pros: 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.
Pros: best performance, dirt cheap
Cons: short lifespan
Mileage: 10000 km
Part number: A103
I just installed a set of Iridium XP 6203 in my Optima 2015 and they're working fine. Gap was incorrect on 2 of them, but was easy to fix.
Pros: working fine
Cons: gap was incorrect
Vehicle:
Kia Optima
Part number: XP 6203
Not saying the auto lite won't work, but you're definitely not going to get 70k out of them.
Cons: short lifespan
Vehicle:
Hyundai Elantra
That auto lite is no goood
Cons: poor quality
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.
Cons: mess up vehicle, not work well
Don't use AutoLite plugs in this car, they are known to have issues.
Cons: known to have issues
Also, Autolite is extra terrible. I would have done anything else.
Cons: extra terrible
