Spark plug BRISK or AC DELCO

I’ve been running Brisks for 30k now and haven’t had any issues

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.

I replaced them with AC Delco 14 Platinums, and it seems to be running better.

Just did mine with ac Delco, gapped them in advance and running great!

In my personal experience (99 suburban 6.2l 383) AC Delco spark plugs are the way to go

I have ACDelcos in my 2010.

I've changed them twice over the 120k or so that I've had the car and I didn't pay attention to what was in it when I bought it, but the person who owned the car before me had a receipt from Advance.

I was running stage 2 apr with rs7 brisk plugs, had misfires on cold start. Did carbon cleaning myself, misfire kept happening. Spark plugs kept getting lose even after torquing. Switched to Oem spark plugs and no more misfires.

Gonna do brisk silver with 4C coils unless someone has any advice on Brisk Silvers being bad. Was gonna try them out over the NGK Laser Iridium

I initially got the P0101 code and did the obvious - replaced the MAF sensor. No change, same codes. Goodbye $100.
