Spark plug NGK or Champion

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

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".

PFR7Q. Hella expensive, but they last for 2 years and give absolutely no trouble.

i use bkr7e in my AWW 1.8t chipped, they work great

replacing the finally worn out NGK PF6Q (stock plugs @ $75.00) that last forever (about 4-5 years, cleaned/re-gapped once)...

I'm flashed with Revo Stage 1 and I run NGK BKR7E plugs gapped to 0.028\". They are 1 range colder and are cheap ($15 for 4 at Lordco if you have a discount). Only downside is that you should regap them every oil change, and change them ever other oil change

I got some NGK DCPR8EIX's and gapped them to .022" and took them for a drive and they were fine. Then this morning on the way to work I did a 2-3 gear pull and got some misfires after my 2-3 shift.
