Iridium spark plugs?

If you can present a logical explanation, Im game, but to the best of my knowledge, platinum plugs dont conduct as well as your standard copper core, and retain more heat, both bad for performance.


And you must quit believing everything you read in a magazine, MM&FF or not. They lie most of the time, and they are paid by advertisers, whos products they push, which produces results that are fudged. 8 hp from a "dyna coil"? The late model factory ignition system is very efficient, and I dont buy that much gain from an aftermarket ignition, especially on a stock car.Hey, I got some beach front property Ill sell you real cheap....its in Kansas.

what would happen if they just put brand new plugs in it instead of the platiniums? probably the same thing.

as for MACH, he hits the nail right on the head! dont care what mag you are reading, you cant believe everything. ever realize how many ads that are in MM&FF issue? more than articles about cars itself. why so many? how else would you make money? use you best judgement when it comes to reading any car mag.
