Spark plug BRISK or OEM Subaru

Brisks are great plugs. Do be warned however, their groundstraps are softer than others and open gap much sooner vs other plugs. So you'll be checking them much more often and changing them sooner than the usual 10-15k tuned interval.

I went to Brisk ER12S a few weeks after going 1+ tune which are one heat range colder, same fitment as MK7.

Brisk plugs off Parker performances page. The brisks hold there gap and seem to really last

Normally that's a result of a failed spark plug seal. If you have no other problems I would put new spark plugs in it and check them at the next oil change.

I'm running brisk One step colder plugs at 0.024 Gap with my eqt stg 2 tune. they are amazing

Brisk LGS plugs basically remove that L shape off the spark at the end. I would expect it act more like plugs do when we index them to the fuel flow. such that you get a better flow in the combustion chamber more consistently.

Since then I have take good care of it, replaced the brakes on schedule in August 2020 and then in August 2021 new spark plugs.

We just got the 60k service done (spark plugs) and it still does it.

would suggest plugs, RS7 or Brisk 12's (cheaper) but coil packs are not needed.

a spark plug job on an STI can be a 6+ hour job :thumbdown:
