Iridium Spark Plugs..

Hi I just bought a 95 Supra NA and the engine keeps having misfires....I am planning to replace the spark plugs with new ones....But I dont know the best brand of Iridium Sparks.....I've heard of NGK Iridium sparks(serial#?) and the Denso Iridium Sparks IK16-5303. Which of these is a better? Or if there is a better one please let me know.

get NGK 3330's, I use them for my turbo car and they have never given me a problem. I don't know what to gap them for your car but mine is 29, it might be the same but check just in case, go to www.mkiv.com great source for info.
