I didnt believe these would work either so I tested them and got positive results. I put these in my bone stock 08 Nissan Titan I gained over 10whp and torque under the curve. Something odd was going on at 5000rpm on all 3 dyno runs the pulstar plugs dropped off to slightly less than stock whp so the peak power showed a slight loss. We did not reset the computer as reccomended we did 3 dyno pulls with stock plugs put the Pulstars in and did 3 more dyno pulls. We are going to dyno it again after I have run a few tanks of fuel through it to give the computer time to learn and see if it makes more power. The heat ranges are typically higher than FI guys would like but Pulstar claims they do not run as hot as regular plugs so you dont need as cold of a plug. I will let someone else test that theroy.

You could mention that you're a member on here and people are very interested in their product but understandably don't want to spend that kind of money on spark plugs without independent verification of whp gains.

I can't remember what mag. it was but its still on the newstands for anyone interested.

I think results for this will vary depending on the application and the state of the tune of the car before installation. If there is any misfiring in the first place, then I can see these helping - particularly at high rpm. I don't think they'll hurt anything - except the wallet. Not enough data on longevity and reliability. If these don't foul and last longer in FI applications - that would be worth something to me even without any HP gain.

You will see 1-4 HP at the wheels. In a 2007 G35 Coupe. The 10 hp is not a real number for the coupe. But you will get better gas mileage out of them. I went from 14-16 mpg to 18-20 mpg. They do not run any hotter than the NGK's the coupe comes with. If you really want proof of this I can tell you that my car has never seen any temperature related issues. My mechanic works at the dealership installed these plugs and we tested the engine temp.
It went down!
I have some nice engine mods now and I think that these plugs enchanced them. Cold Air, Plenum, and these plugs were phase one. Phase two is a Borla dual exhaust, and high flow CATS. Should be done by the end of the month.
I will let you know what the total hp gains look like.

i know everyone wants to see dyno's,
I don't have any...
But I did get the pulsh*ts
i didn't feel any difference AT ALL, it doesn't rev any faster, nothing... But with that being said,
this mod is like buying anything else, exhaust*assuming you don't lose enough low end power on nonboosted*, intake, plenum, whatever it may be, it's the combination of the all mods that will give the power. Not just the one mod. so if i did everything together maybe I would have felt a difference, but as for now, i kinda wish i had that 160 in my pocket.
regret it.

I have a stillen intake with the Z tube, Z1 motorsports plenum spacer, stillen test pipes, U. O. racing underdrive pully set, stillen grounding wires, and a stillen dual cat back exhaust. i have seen no problems with these plugs.
