It’s confusing. Most gti owners say stock is fine while the rest recommended rs7 plugs. And iirc I think apr recommends a range colder, according to their site.

I personally have no idea but if apr suggests it... 🤷🏽‍♂️

Not necessary for a stage 1 tune.

Yes, looking back I may not have replaced mine with RS3/7s which are colder than OE, is more like a piece of mind - since the car was 40k mi. at the time.

"APR recommends NGK heat range 9 (NGK-R7437-9) spark plugs gapped to 0.024" ±0.002" or 0.6mm ±0.05mm with a change interval of 10-15,000 mi or 16-24,000 km."

Stock plugs call for replacement every 60K, and APR sells NGKs. APR would LOVE to sell you their spark plugs every 10K miles.

On a S1 tune I'd bet you can safely run 40K intervals on stock plugs, or shit you could keep to 60 and just change as-needed if any fail prematurely :) I will be taking the latter route.
