Spark plug BRISK or BERU

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

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.

Check out Brisk Silver Racing (listed as an option by EQT). You’d have to replace them more often vs iridium, but they are super inexpensive and more performance oriented (conductivity).

use beru plugs rather than Bosch, a lot of Bosch plugs sold for this application has the wrong heat range which can cause misfires.

Put the one piece Brisk in so that you don’t have to relive that again.

I ran the Brisk plugs for 6200 miles .. a bit over the 5K recommended interval. Installed Denso 5749 plugs this weekend and maybe I'm imagining things, but it seems a bit less temperamental at highway speed passing pulls. With the Brisk's installed lately I was getting some hesitation with WOT. No more.

Call me stingy, but I have an issue paying $40 for 1 spark plug. Especially when I can run a set of Brisk Racing Plugs for $60.

Had these Beru plugs put in last year. Are they the kind that’s at greater risk for damaging the engine?

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.
