Working well.
Different socket them stock. These ones are 5/8. The old ones are 3/4.Seems like a better idea to have the smaller drive setting as its pretty tight getting on my plugs.22RE Toyota engine.

Worked perfectly on the 2013 audi a4 Quattro (B8.5). They eliminated the hesitation/lag caused by the old plugs. My sister said the car felt much zippier and smoother. I’m not surprised as the old plugs looked like they were in there since the car was brand new. YIKES. The gap was too wide, and the electrode was completely round from wear, instead of having a sharp tip. Needless today, these were necessary.I changed all 4 ignition coils (Bosch/OEM always for those parts) a few days after installing these, because the check engine light for cylinders 2 and 3 misfire did not disappear. I changed all 4 ignition coils because at 160,000 Kms, German cars usually need new coils in my experience. And seeing as the car has only 4 cylinders, losing even one cylinder makes it quite dangerous to drive.Final note: I placed all 4 plugs side by side before installing and they all had the same gap. This is what I usually do and it hasn’t failed me yet. I do not like gapping them myself because it isn’t as accurate as you think. I’d rather exchange them at that point.
