Spark plug OEM Toyota or BRISK

The ER12S look better than the OEM units that came out on the first change, these have been in for a year.

I've ran these for a few years stage 2 e85, with absolutely no issue at all. The last year and a half I've been running a bigger turbo, powermax 2260 and have had zero issues

Been running them for the last year on EQT stg 1 91 and e30 with no issue.

Check out Brisk Silver Racing (listed as an option by EQT). You’d have to replace them more often vs iridium, but they are super inexpensive and more performance oriented (conductivity).

I have an 02 4runner with 289,500 miles. I've had it for the last 106,000. Replaced the timing belt/ water pump twice. Replaced spark plugs twice. New brakes a few times.

Put the one piece Brisk in so that you don’t have to relive that again.

Unfortunately no--replace them. The electrodes wear down and become less efficient. The good news is that iridium plugs have a tremendous lifespan. You're supposed to change them every 100k miles/167k km.

Bought a 03 100 series with 241,000 only issue was the number 7 spark plug blew out, had to re-tap it and install a aluminum sleeve, and replace the coil

Call me stingy, but I have an issue paying $40 for 1 spark plug. Especially when I can run a set of Brisk Racing Plugs for $60.

I wouldn't do the Brisk plugs if you're not tracking it hard. They susceptible to fouling up unless you drive it like you stole it every time.
