I'm reading an ad in the back of autoweek magazine that is an ad for pulstar spark plugs and it shows a dyno grapho of a nissan 350z increase of 11 horsepower and similar in torque.

The 350z makes less horsepower than the h2 especially the 08 h2, would spark plugs like these or similar give +15 hp to the h2? Plus importantly better gas milage????

They got all sorts dyno results on their blog at http://pulstarplug.blogspot.com/ Anybody used these or have ideas? I would surely change right away for 15 horsepower and more importantly gas economy on the h2 limos.

Have no idea, but if you're changing your plugs anyway what could it hurt?

There's no way a plug change will give you a big HP or MPG gain on a stock engine, GM would've done it. They kill for every 1/10 mpg. Put a good quality plug in it and save your money for other mods.

I have NGks plugs and Taylor thunder volt wires, and they work just great, and not $25 each!! as for more MPGs or more HPs?? Who the heck really knows, they say it should increase, I say I don;t really have a clue, nothing that jumps out at you at least.
