Spark plug OEM FORD or BRISK

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

New plugs and a fuel filter are all cheap and easy maintenance items that no ones done.

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.

I just fixed a shift issue in my 2011 by changing the spark plugs. The plugs were so worn they were draining the electrical system. Lights brighter and Stereo is louder in left channel now too.

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

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

Stock Ford ones were $9 a piece at my local dealer…

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.

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.
