Yes, i have a g2 supercharger kit 14psi with rktune. Was having spark blow out issues with oem ngk plugs. Put 97506 gapped to .20 and car pulls normally now.
No point in going to colder plug unless youre running built motor level boost and your car is cutting out during wot pulls. Spark blowout Feels like hitting redline.
