ok so i've been researching spark plug upgrades and i stubled across Pulstar pulse spark plugs. They claim to boost HP, torque and fuel economy but they are kind of expensive so i thought i'd see if anyone has tried them and what results they had?
I noticed a little bit of improvement with a new NGK wireset but not enough to justify $100 for four new plugs. If you've got money burning a hole in your pocket, fine. But don't go out of your way to save up for them. NGK Iridium IX plugs are also good.
