I have read dyno results of the Pulstar plugs. Its a load of crap. Some of the results even showed a loss in power and torque. You know theres a chip on ebay, that will give your car a 50 HP increase and its only $20.
Wow, you guys are so harsh. Alright, gotta go install my Turbonator intake for the 5mpg and 25hp increase. Just wish I didn't have to remove the Platinum grounding kit (+10hp) to get to them.
