Iridium plugs are better then platinum when it comes to any type of FI. With Nitrous, however, you have no choice in the the matter. Platinum plugs will not hold up and will eventually melt!
Go with NGK iridium in any FI VQ motor, its a better choice.
Also ALWAYS GAP YOUR SPARK PLUGS!!!!!!! I cannot stress that enough. It only takes a couple minutes, but its critical to have the correct gap. They do NOT come pregapped. There are tons of other applications that these plugs work for, so you cannot assume the gaps are for our cars. Hope this helps

When I got my iridiums in, most were pretty close, but pretty close doesnt cut in my book. You need to be exact and to make sure ALL the cylinders are running as close to each other as possible. So i adjusted the plugs accordingly and so far its been problem free with multiple runs and as my daily driver.
my 2 cents
