Has anyone used the Pulstar Plugs, if so have any data? I have used them in a '03 and '05 Cadillac CTS, and an '05 Altima, all with tremendous gains in efficiency and torque performance. I researched the temp for them and found that they are much cooler than most (equivalent to the NGK-7 or so). I did install a set the other day, gapped at .028. So far, they are doing GREAT! Was just wondering if anyone else had tried them?

Most on here use the NGK plugs, I'm not knocking the Pulstar, I just don't know anything about them.:zlurking:

I had noticed that, and I have nothing against the ngk at all. My dad is an electrical engineer and did a TON of research on the Pulstars and has used them in all his vehicles for many years now. So, with his recommendation and my own looking around, I went with those.

Not to start a debate, but how did you determine the "tremendous gains in efficiency and torque performance"? Unless there is a misfire problem, which there should never be in our cars unless there is some other problem, I have yet to see any miracle spark plug make a discernible difference in any car I have ever owned. When you say "they are much cooler than most", are you referring to heat range? All spark plugs come in a variety of heat ranges, so that is nothing unique. Having an extra cold plug is of no advantage and will tend to foul sooner.

The gains that I have personally noticed were all in automatic transmission vehicles. (The Caddy’s and the Altima all got 10-16% better gas milage and felt more like constant velocity transmissions.) It’s more of a personal preference, that I like the Pulstars, and nothing more. I was just curious if anyone else had tried them. If I do happen to have a problem with them or notice anything spectacular happen with them I will post the info as soon as I can. As far as the heat range, most of the folks I have talked to, or read about on here are using the NGK6 range, and the Pulstars tend to be a tad cooler. I will keep an eye out for misfires or any other indications of problems.
