Here is some more information on the Pulstar Plugs. I have to say, if the dyno results be believed (and I have no reason to doubt them) the plugs give some gains, but they are not gains that would be indicative of the sales pitch. That said, perhaps the Pulstar plugs would perform better in a higher voltage ignition system such as one in which higher energy coils were used, lower resistance plug wires, and perhaps some upgrades to the overall electrical system to make sure maximum voltage was getting to the primary side of the ignition.
However, even with that, I would not yet be able to justify the $150 it would need to outfit a 3800 engine. Now, if they were to bring the cost down to the area of Brisk or E3 plugs or give me a set to try and report back (Id even send them back if they desired) I would certainly do so out of curiosity.
If the horsepower gains could be pushed to 10 - 15 or so, it might be a more viable option. I tried like crazy to get a set of Nology hot wires for my last vehicle because capacitive discharge ignitions make sense to me and I understand the idea and use. But Im having a hard time grasping the Pulstars because of the numbers they use (they just arent possible in a modern vehicle) and I have questions about the reliability with the heat they would be exposed to.
