Spark plug NGK or Denso

I got the plugs in just fine, and since this was the first time they had ever been changed, the originals were still there. Aside from having the Audi/ VW logos printed on the topside of the plugs' insulators, these are regular ol' NGK PZFR5D-11 plugs (stamped on the metal). The new ones I put in were pre-gapped at .040, and the old, worn ones were at .044 for the passenger-side plugs and at .043 for the driver-side plugs. I'm guessing that the elevated distance/numbers reflects natural wear and metal erosion over time.

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

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

I swapped out the plugs using the DIY thread for reference. The BKR6E have been fantastic so far. I can feel the difference in power band. I mash the throttle and there is very little hesitation. Prior to the install, the engine would think for a second, then go. Now, even right from the light, the car just want to "go".

Napa usualy is the only parts store around me that carries NGK in stock

I went out bought the NGK plugs and installed them moments ago. Reset the codes and started the engine. Within 1 minute I had the CEL and the P0351 - P0354 codes.
