Denso Iridium vs. NGK Iridium vs. Pulstar Pulse? Which Way???
Well been reading a lot of reviews on spark plugs. Been comparing the Denso Iridium vs. NGK Iridium vs. Pulstar Pulse. The Pulstars are showing most torque and HP gains with about 12-14 hp gains while the other two are about identical in results between 8-10 hp gains. However, the pulstars are about twice as expensive as the denso's. Right now I currently have the AC Rapid Fire's. Thoughts anyone??? Anyone ran any of these plugs in their's? What kind of results did you see?

There are so many factors. If your spark plugs that you have are in good shape, properly gapped and are in the appropriate heat range, then I don't think you will see a horsepower increase by switching to a different spark plug. If your spark plugs are beginning to foul, if the gap has closed or if they aren't the right heat range for your application, then you could very well see a horsepower increase by switching to new spark plugs. I think that is more a function of having a new, properly gapped spark plug than it is of using a different brand.
At least this is what I typically hear from automotive engineers.

Makes sense completely, however, the AC plugs are platinum while these other brands are iridium which claim to deliver a hotter spark and better fuel efficiency.

If you pay over two bucks for a plug your getting ripped off. You cannot beat a regular AC or Champion plug for performance. Many so called performance plugs are on the same caliber as snake oil. All my records were set with regular plugs donated by Champion or AC. Nothing out there could make my cars go any faster because if there was I would be using them, as winning isn`t everything, its the only thing....
If you buy those fancy plugs, all you did was buy into there marketing
