Spark plug BRISK or Motorcraft

Some people swear by the Brisk plugs, but I'd spend that coil money on either the Denso or NGK plugs that EQT recommends.

I love my brisk spark plugs from EMS. Definitely better for me than the NGKs I ran. Last longer and don’t open up as fast.

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

Oem Motorcraft plugs are always my go-to. They generally last around 80k miles.

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.

Has anyone tried the Motorcraft SP594 plugs? They supercede from the SP542, which is said to be a 1 step colder plug for our cars. Currently running NGK 6510s but i think i got a "fake" set as i paid like $30 from Amazon for them. The SP594s I can get for $41 from Ford... so anyone have good results?

What plugs you're using may help. In my experience not all plugs are created equal. Brisk, for example, last maybe 5-10k miles before they're garbage. Whereas I can run NGKs for 15k+.

Brisk silver er10s if you need 2 steps colder. I had the ngk plugs, but they wore down just as fast and are more expensive. Brisk silver are like 10 bucks

Also I would stay away from Brisk ER12 spark plugs since they require higher change intervals (And risk of damaging coil packs) @ 3-5K miles as opposed to NGK R7437-8 or NGK R7438-8 @ 10-15K miles.
