How's the gap on #4 vs the rest?
within the range of -10 to +10 for fuel trims is normal. STFT might be more sporadic, esp when you let off gasYea, I walnut blasted intake valves a few months ago, they clean! Haven't seen any fuel mileage drop, I've been monitoring STFT and LTFT lately but I don't really have a baseline so im not sure what's normal vs what's not. Maybe @Diggs24 can have some input on this. This is what the er10s look like coming off the car yesterday:

Though, looks like they are running hot.
All but cylinder 3 are about 025, 3 is about 024How's the gap on #4 vs the rest?
Under normal driving im usually +/- 2 with an occasional +/-4within the range of -10 to +10 for fuel trims is normal. STFT might be more sporadic, esp when you let off gas
I see what you mean about off to the side, #1 looks a little off as well. Would incorrect toque cause this? I torque each to 18ftlbs using my torque wrench.Was it torqued properly? The insulator staining is off to the side on #4 vs the rest it is under the strap. Coloring on #4 looks different too.
Should be 22 from memoryI see what you mean about off to the side, #1 looks a little off as well. Would incorrect toque cause this? I torque each to 18ftlbs using my torque wrench.
30 NM or 22 ft/lbsShould be 22 from memory
Well damn, I’ve always torqued to 18, possible that was the spec for the MK6. Doubt it makes a difference, but maybe I’ll bump them to 22ftlbs when I get home.Should be 22 from memory
Do you have an example of what the plugs should ideally look like? For all intents and purposes the plugs look pretty clean, but I’m terrible at reading plugs.Electrode looks a bit burnt too. Coloring might be because it's touching the ceramic there. I'd keep an eye on the Densos and see how they look in a few k.

Why. I could understand a reverse stagger, but different size wheelsJust got these dropped off today. Yes, they're 2 different sizes. Intentional.
