Spark plug BRISK or Denso

I've always used the Denso SK20R11 plugs in mine and been pleased.

Denso iridium plugs, no more no less and no exceptions.

denso iridium. do them and they’ll be good for another 200k km or more

The ER12S look better than the OEM units that came out on the first change, these have been in for a year.

Denso and Bosch have worked well for us on a 1.6.

Denso itv20 (5339) for stock/mostly stock. ITV22 (5340) step colder if more mods. I have only used itv22 since 2015.

I've ran these for a few years stage 2 e85, with absolutely no issue at all. The last year and a half I've been running a bigger turbo, powermax 2260 and have had zero issues

Been running them for the last year on EQT stg 1 91 and e30 with no issue.

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

Skip them, they are junk and a waste of money.

Get a good single platinum plug like the Denso 4511.
