vs
Spark plug BRISK or OEM Subaru
Reviews
Some people swear by the Brisk plugs, but I'd spend that coil money on either the Denso or NGK plugs that EQT recommends.
Vehicle:
Volkswagen Golf
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.
Pros: last longer
Cons: open up fast
Vehicle:
Ford Focus
The ER12S look better than the OEM units that came out on the first change, these have been in for a year.
Pros: look better than OEM
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
Pros: no issues at all
Been running them for the last year on EQT stg 1 91 and e30 with no issue.
Pros: 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).
Pros: inexpensive, performance oriented
Cons: replace them more often
Put the one piece Brisk in so that you don’t have to relive that again.
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.
Pros: null
Cons: paying $40 per plug
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.
Pros: no more misfires
Cons: misfires on cold start
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.
Cons: higher change intervals, risk damaging coil packs
