Spark plug BRISK or Motorcraft

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).

Modern Ford engines tend to work best with Motorcraft or NGK spark plugs.

Motorcraft is all I use , heard to many stories about aftermarket plugs causing 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.

I went with [Brisk ER12s](https://www.fcpeuro.com/products/vw-spark-plug-brisk-racing-er12s) plugs. They are one of the plugs recommended by EQT and I have been happy with them so far. Cheaper than the NGK/Denso plugs but downside is that they are silver based, so they will wear out faster. I am at 10k miles on them now and starting to feel a little rough idle; time to re-gap or replace them.

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

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.

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.

I wouldn't do the Brisk plugs if you're not tracking it hard. They susceptible to fouling up unless you drive it like you stole it every time.
