I got my New Dsport Mag, and also there's a couple of articles on the Web about this Spark Plugs, With they really work well with F/I Aplications!

I they really do work well carn you imagine Okada Coils with These Plugs working toghether!

those plugs suck!!.... and no, I have no evidence to back up my opinion other than reading alot of bad about them awhile back! poor build quality and did not dyno anywhere near the claims.

 

dont waste your money.

 

LOL

 

These plugs have destroyed a few Evo engines already; they've pretty much melted/self-destructed in otherwise perfectly running engines and take out pistons, valves, etc. in the process. IMO, nothing beats a good NGK spark plug (your choice of in variety).

 

i got excited about these too when i read the article, yea but the claims they made were insane, and it never happened

 

this was done back to back on our dyno. we took the best of each run and the difference was a gain seen across the entire power band. (NA)
stock plugs is the blue line and the pulstar is the red

 

Hard to deny first hand data over hearsay. Now I need some proof these are reliable and won't melt my pistons before I experiment. My inclination is that these are more reliable in an N/A application over the hotter high pressures of FI.

 

how many miles on the stock plugs? Generally people can swap in new plugs and get the same kind of results.

Swapping in fresh plugs is an old dyno trick to pick up a few ponies

 

I have been using the Pulstar plugs now for the last 10000 miles with no problems.
I can verify that the plugs do increase gas mileage, and they make the car at least feel more responsive and powerful if not in reality, but I would not doubt that they have increased my horsepower/torque over stock plugs, I wish I had dyno'd before and after but I don't care much about numbers, just performance and feel.
These plugs deliver on that front. YMMV. I give the plugs a tentative
I have not heard of the problems others have had with the plugs causing engine failure. As I have said no problems here. You just have to be careful during installation and not put any lateral torque on the porcelain, as it is spaced some from the metal hex surrounding it and it is prone to breakage if you put lateral torque on it. Just start the plugs by hand using a spark plug socket then carefully tighten to specs, using just a normal deep well socket without the rubber insert found in spark plug sockets and without lateral movement. Make sure you gap the plugs to spec before installing, they are not pregapped properly from the factory, (which may explain some other's lackluster gains) and after installing plugs do the "idle relearn" procedure. This worked well for me.
