I just got done installing pulse plugs in the Z and took it for a quick run, and it seems like the RPM's rise alot quicker, and you can really feel the engine rev, for the most part, it's got some extra kick that you can definetely feel or it may just be me.

youll always feel the results of new plugs, but whether you would have felt more from your 150 plugs vs a 60 dollar set of iridium plugs that all in your head

Feel-good reviews such as this are really worthless when it comes to new technology where objective data is required. It's not like the sound of an exhaust, or the looks of a set of rims, where personal preference is the primary judgment criteria. It is highly unlikely one can feel 2HP, even if plugs could make that much difference, especially with the green, naive type of drivers that are so commonplace here today. I'm glad the OP is happy with his investment, however nobody with any common sense would go out and purchase these plugs based on this review.

i have too much money and i was just curious about them, and i wouldn't call this a review, but whatever.

I can think of a solution for this.....

Okay, then here's what we all need. First Dyno the car. then swap those plugs back for a new set of NGK's. then re-dyno the car....NGK's are the cheap part.

... then buy me a TT kit and pay for the install and the before and after dyno's.

that'll set you back a pretty penny.

and get me a #5 at whataburger.

Good enough for me, I wasn't hating your reason for buying them, but we have seen several threads on this recently, and I was hoping we would see some objective results.

I use plat 5As or G LFR5AGPs--coppers---Dont split hairs-----NGK makes a great Plug

pulse plugs were tested in Dsport mag march 2008.
VQ35 engine unmodified gain 5.2WHP.

so much hate around here, am running these too and you would have to be a complete moron not to notice the subtle change these plugs bring. throttle response is excellent...have fun with them man!

I think u r lying to urself, have an extremely sensitive butt dyno, or r a complete moron if u think u can actually feel a claimed 5 whp gain on these motors.

still waiting for some actual complete and objective testing of these plugs. Taking out stock plugs with 50k miles on them and then installing and dynoing the pulse plugs is not complete and misinforming. Dsport should have done testing on a variety of performance plugs like ngk iridiums, which are a 1/3 cost of the pulse plugs; like the srt4 test.

its not hate but just past experience on this car with knowledge from doing swaps already. of course throttle response will be faster with ANY NEW PLUG. show me a dyno and then ill believe you.

am not saying you'll be wowed by these plugs, but you can notice a peepier response. I was running NGK IX before these. I was trying to call anyone a moron either LOL just trying to put a little perspective in this mod...its nooothing like a spacer or TPs where you can notice significantly. thats why I never went around boasting about them.

This is the bottom line ---I refuse to spend 150.00 for plugs unless they come with a BJ

So, there still doesnt appear to be any response with testing one NEW set of spark plugs, NGK IX would be nice, and these NEW pulse plugs. If anyone has tested this please post a pic of the results...

Id like to know because Im starting to add mods to my car and was wondering if this would be worth the $150 cost of adding these pulse plugs.
