ive been using the RS7 spark plugs(Gapped properly) and swap every 10k miles, but nowadays I do not run very hard, just cruise and occasional hard accelerations. Paired with APR coil packs, havent had any issues.
Pros: no issues
Vehicle:
Audi RS7
Mileage: 10000 km
120k miles on my 2015 a3 with a stage 1 tune. I did timing belt, tensioner, and water pump around 100k miles. Costed me like $1k. Also did spark plugs and a new battery, which was another $600.
Vehicle:
Audi A3
Mileage: 120000 km
Within the last 8,000 miles New spark plugs
Pros: new spark plugs
Vehicle:
Audi A6
Mileage: 8000 km
Changing my sparkplugs for the first time (32k miles, yes it's early but I got a great deal on the plugs) and found that the stock plug in cylinder 4 actually had a ground electrode defect and was significantly thicker than normal. The car runs stronger than it ever has as this was likely causing extra timing pull.
Pros: car runs stronger
Cons: ground electrode defect
Vehicle:
Subaru
Mileage: 51500 km

I’m IE stage 1, had the plugs changed to rs7 plugs I had been waiting to Install (they were early versions) not long after, left the shop and had horrendous misfire. Limped back to the shop and got OE plugs back in and it worked fine.
Pros: worked fine with OE plugs
Cons: horrendous misfire
