These plugs are working flawlessly in the Subaru I installed them in one year later. No issues of any kind. Great product. I would recommend them to anyone looking to do a spark plug swap.

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.

I had an issue with 1999 Camry having rough idle when in drive mode and stopped either at a stop sign or at red traffic light. The issue does not show up when driving. Since I had replaced sparks plugs this year in January, I was not considering the sparks plug as an issue. So, I replaced fuel filter, air filter, cleaned throttle body and replaced PCV valve without any luck. At last, I ordered these spark plugs and once replaced the rough idle issue has gone forever. Wow now that is a relief since I was working on the issue for 2 weeks without any progress. Now I can relax and focus on something else. So yes, these spark plugs are perfect if you are looking for the same and have any rough idle issue with your car.

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.
