Have found NGK 4179 to work ok and has a solid top like the stock plug so it can’t come loose and alter resistance readings.

With ion sensing I would not use an NGK 4179, I have in the past and have found up to 5° knock retard because of detonation while data logging... At least the system thought it was detonating but there was no evidence on the plugs but yet my timing was being held back.... Stick with the 6R12...
