Denso was 360 for 4.

NGK is 100 for 4.

Before spark plug failure i was over 260km/h

Now have a 10bhp reduced Stage 2. Catless DP

Denso did not break the engine. It was skipping ignition at a certain RPM (somewhere around 4.5k) which made the car jump.

So sorry for your car bro. Is that about the timing and the octane? Are you using alcohol with 95 or is it only 95? If this was about the timing and octane, then we should use a boost controller like profec. When we sense any timing problem, should reduce the boost. with a boost controller it is so easy. Ofcourse, when we running with alcohol, we could maximize the boost.
