Spark plug Autolite or BRISK

Get a Brisk spark plug. Worked for me

Been using the cheaper Brisk brand and never had an issue for 20k miles.

Almost any spark plug is better than the Torch it comes with. The recomended is the NGK BP7ES, but is not made any more, many use the BPR7ES without issue, which is a resistor plug, but the manual specifically says to not use a resistor plug. I am using an [Autolite AR52 plug](https://a.co/d/7Z3keDh), it crosses with the stock Torch and NGK BP7ES and is a non-resistor plug. Many people hate Autolite plugs, but I have been using them for years in other vehicles and never had an issue, and so far it is working just fine in my 11500.

I replaced the spark plug with an Auto Lite spark plug. Engine light went away but still runs rough and misfire on acceleration.

Brisk are fine. You have to check them about every 5,000 miles. And change out sooner than other brands.

Do not under any circumstances put autolite spark plugs in anything you care about. Worst of the worst

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.
