Well, I have tried them out before. After reading their website on their technology, like pushing the spark to the side for better combustion. Small tip for more intense sparking and so on. To me nothing much to feel....:smokin:
Even feedback from members are like smoother drive, some say better pick up but these are all butt feel. Or better you google on spark plug and read for yourself.

What I can say is for those people driving car that changing plugs are a pain in the butt, better use Iridium.

are you still using 4G92 SOHC ECU/Map sensor ? How about throttle body size ?

Since you are on 4G93 SOHC block now, next thing might even poison you more will be DOHC head...follow by GSR Turbo kit...all mostly plug and play..you will jump from current HP to 200-300 HP easily.

Oh! now I read it more clearly, means the whole engine change to 1.8 but using 1.6 harness. This way you engine will still run as a 1.6 system, probably not enough fuel.
Changing to larger displacement best should get half cut and transplant everything....:driver:

The only way to know if your current setup have an ideal Air Fuel Ratio is to use a Wideband O2 sensor and measure the AFR. It can be done on-road or on a DYNO.
If slightly leaner.. just add fuel pressure regulator and bump up the pressure a bit.
I think a lot of mechanics these days have a wideband kit ready at their workshop.
For one I have it. I charge RM30-40 for AFR monitoring on-road. Or the more expensive way; a DYNO RUN
