Owner reviews for spark plug

i just replaced my plugs and wires from ecs not too long ago. right around mid june. i got NGK plugs and wires, plug type was the one u listed there, i have an AVH. the wires i got were numbered wrong just a heads up to anyone that buys them.

I prefer the NGK 8 or 9's, running them at 19 psi gapped at .018.

I've left the plugs in and the car fells like it did before. I could have just become accustom to the way it feels now but that "sense of emergency" when I hit the peddle is back.

I am stage2+ and changed out the coilpacks at the same time that I went with NGK. I never did a side by side comparison, but so far i like the NGK's

i havent noticed any drop in performance..runs smoother though like you said, and a little better fuel econ too

If you look at the other forum post u will notice that Pete alreAdy dynod them and noticed a difference. oh and car runs amazing @ .042

Just replaced mine with Denso Iridiums, seems to be doing good.

yeah ive ran them.... i guess there ok but they foul faster then the iridiums...

Personally I've never had any luck with ngk's in any of my vr's always just run Bosch plugs and wires....

a spark plug job on an STI can be a 6+ hour job :thumbdown:
