Sparkplugs for tuned Supra

[B58_ hwAyaq]

Looks like stock plugs are good for most tuned applications, but would the recommended interval change? US manual looks like 30k intervals. Any recommendations for spark plug interval for tuned applications?

97506 plug are NOT for B58. Do not use them. Just stick to the stock plugs andntock gap

Stock plugs, stock gap. It's not 1994 anymore.

I have been running OEM Champions 600whp+, no issues.

Only small thing I had was some break up past 30psi. I just increased the coil charge table a smidge and it cleaned it right up.

Stick with Oem Champion plugs or if you want NGK it's the 96206

Before the oil face off starts, since you're catless running e30 mix just go with a 5w30 or 5w40 that has BMW LL01 approval.
