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?
