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

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

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
