Hey everybody,
I was just wondering if anyone has tried out the Denso or NGK iridium plugs on their NA Supra? What do you think about them?
Thanks

I have them in my na, and I really like them. Great throttle response, great acceleration, and great idle, I dont really know about the increase in gas mileage....although I cant really bitch right now with 29.8mpg on highway. Would definately recommend a set.

I went with the Denso Double Platinum. The only difference between the Platinum and Iridium are the amount of miles you will get out of them. 60,000 for the Platinum and 100,000 for the Iridiums. You might get a little hotter/better spark from the Iridium but I would recommend some Magnecor Spark Plug wires with the Iridiums.

The part number for the Monarch website is IK16. That's all you need. They are $11.99 a plug.

Sorry if I might have asked this before, but....if I get a HKS Twin Power and some 8.5mm wires, will this be too hot for the Denso Platinums which I got from toyota? theres maybe 1000 miles on the plugs if that.
