I use these in my IE stage 1 MK7. I replace them every 20k, zero issues so far. They could probably go another 10k miles, too, I just replace them early to avoid the ground strap issue that seems to be prevalent.
Pros: zero issues so far
Cons: ground strap issue
Vehicle:
Volkswagen Golf
Mileage: 20000 km
When I order NGK spark plugs, I get NGK spark plugs, not some copy.
Pros: get NGK spark plugs
Vehicle:
Honda
The AC Delco Iridium are fine failing that anything NGK the NGK ruthenium work well. Or the NGK Iridium
Pros: work well
I replaced all spark plugs with Genuine Audi NGK plugs and replaced all Ignition Coils as well.
Vehicle:
Audi A6
After changing: Idles better and more consistent at 700~800 rpm range. Car drives smoother? Changing spark plugs made it visibly better.
Pros: idles better, drives smoother
Mileage: 215000 km
NGKs are my go to’s
Pros: go to
Also check the spark plugs, sometimes people are cheap and buy autolites instead of NGK. Cheap plugs from previous owner give me a headache.
Cons: cheap plugs headache
I’m lucky if I get a full 5k miles out of a set of ER10S before one of them shits out and I get a misfire.

Cons: misfire, short lifespan
Mileage: 8046 km
Part number: ER10S
I changed my plugs for NGK IRs but now I have a rough idle when the engine warms up.
Cons: rough idle when warm
