As promised I told you guys I would get you dyno information on the pulstar plugs we had ordered to test. My boss has a 2007 SRT8 Magnum, it has exhaust, intake and a reflash. We did two base pulls this morning which came out to be 394hp and 396ftlbs. Both pulls were within tenths of eachother. My boss and I quickly changed the 16 plugs and did 3 pulls after that. The car had cooled down a bit so the first pull got us 20 more ftlbs of torque, but lost 2hp. We had done two more pulls after that. We were very dissapointed to see that the hp loss was not made up once the car was warm and that we only gained 4ftlbs of torque. After we got off the dyno and drove home. We noticed A LOT of static through the radio and no physical seat of the pants increase. I feel that for 200+ dollars for plugs and only 4tq and -2hp is not worth the money. I hope this helps everyone out. Sorry for the dissapointment. And happy motoring!

we were rather excited to see the jump in torque on the first pull. we had high hopes that i would stay up there. but after the second pull when we lost 16. we realization came true. I guess if it sounds to good to be true than it probably is.

i think its because the car was colder than when we did the first two pulls. right on the verge of going into closed loop. but not actually being there. so it made good power

I recently did a dyno test with these plugs and got just about the same results you did. I had a small block Chevy with a carb as a dyno mule and saw about four horsepower of improvement, which to me isn't enough to justify the cost. I wonder if the plugs were too hot for your engine setup and causing detonation?
If anyone is interested, I shot video of the dyno test. You can see it at Dyno Testing the Pulstar Plugs | StreetMuscleAction.com.
are you talking about spark plugs right.me dummy.if so what is the best high performance spark plugs for this 05 and up gt that are moded.or are the factory one good enough dont hear much about them on here.
A couple of weeks ago the my website blew up, and in the process of fixing it my web guru changed the permalinks somehow. Anyway, the old link won't get you to the video if you clicked on it. Here's the new link if anyone is interested.

you would think those plugs come pre-gapped, but they do NOT you know?. I threw a set into my 2011 mustang this week and it it running like champion Horse of the year.
