Spark plug OEM FORD or Autolite
Ran Autolite Iridum XP XP3922 plugs in it and had zero issues at about half the price of the NGK plugs, and I had a mild tune.
I just fixed a shift issue in my 2011 by changing the spark plugs. The plugs were so worn they were draining the electrical system. Lights brighter and Stereo is louder in left channel now too.
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
I bought some Autolite double platinum spark plugs because they were on sale at the Napa where I live but everybody I have tried asking to help me do my spark plugs has gawked as soon as I say "Autolite" and tells me that I'll have nothing but issues with those plugs and that "they're only good for Fords" basically.
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.
Don't use AutoLite plugs in this car, they are known to have issues.
