Plugs for supercharged NA
I am going to replace my plugs in my M45 supercharged 1.6, What should I use?
I have been told with the supercharger to go one colder and just have standard NGK,S in there at the moment. When the car was n/a I ran plantium plugs and thought they were great so would like to go platnium or iridium again. I have no problem spending the extra money.
I asked this question on a USA forum and there suggestion was a IRIDIUM NGK 6988.
Does these numbers make sence to anyone or do these plugs come under a diffrent number in NZ?
Also where is the cheapest place to buy from?

Basically it means you dont have one coil per plug. One coil fires two plugs at once. Some of the spark energy travels to one plug then through the head and back to the coil through the second. Thats a really basic way of looking at and doesnt fully explain it but you get the idea.

i think if youve got something that requires anything more than a 7 plug , then you SHOULD be running Coil on plug setup first. the factory coils are woefully underpowered. as a very first step the power and earths for the coils needs upgrading and the power feed needs to come from a relay located next to the ignitor and fed by heavy gauge wire from the alternator. the volt drop in that factory loom is excessive.

Sorry mate,
Going to have to disagree with your synopsis on the MX5 coils
I've found the MX5/EVO (Part No. TIP012)Wasted spark coils, to be some of the best on the market
To the point I fit them to all the big power RB and Turbo/Supercharged Lexus V8 Engines and always eliminates any spark blowout problems.
They can easily handle up to 6.0ms of dwell, when the Toyota COP setup are maxed out at 3.0ms maximum, and happiest at 2.5ms, anymore and they over and can explode (guess how I know)
You only have to feel the difference in weight between them to see how much extra copper is in the MX5 coil setup
You are dead right about the power supply to them in the MX5 - it's just a freaking joke, and I reckon is pretty much the cause of 90% of sparkblowout issues.
Saying that I run COP in one of my MX5's and sell the COP kits, but it's more for aesthetics than anything else
