vs
Spark plug BRISK or OEM Mazda
Stock is generally fine, however if your tracking or going through multiple heat cycles on your drives id recommend er12s from brisk. I run them and they havent skipped at beat. Intervals are shorter for changes.
Pros: havent skipped at beat
Cons: shorter change intervals
Part number: ER12S
Just did mine at 69k. Felt like a small pickup in performance.
Pros: pickup in performance

Mileage: 69000 km
Bought a used 2014 CX5 with like 250km on it. Changed the spark plugs the second I bought it. Now THOSE were due.
Vehicle:
Mazda
Mileage: 250 km
I’ve had my cx5 since August of 23. Put 48k on it since owning it, bought used at 44k it’s been a dream come true. cx5 just takes regular maintenance like oil changes spark plugs and brakes..and another plus it’s a very sharp looking vehicle inside an out.
Pros: sharp looking vehicle
Vehicle:
Mazda
Mileage: 77249 km

Pros: work great
Spark plugs, coolant exchange, transmission drain/fill, brake fluid flush, and air filter replacement, stat.

I recently took my stage 2 43K mile b8.5 s4 apart and did the PCV, water pump, thermostat, new 2 step colder brisk spark plugs gapped to .25. I took the spark plugs out and noticed heavy carbon and the ground electrode was white, even on all plugs . (20 miles on plugs)
Cons: heavy carbon, white electrode
Vehicle:
Audi S4
Mileage: 69202 km
That price at 63.5k miles isn't bad imo. I spent roughly that same amount for my 2017 back in 2019 with around 40k miles (64k km). What's the service history look like? Have spark plugs been replaced, belts checked, engine oil changed at least 10-12 times by now? How are the pads and rotors?
Vehicle:
Mazda
Mileage: 102200 km
I just run oem plugs gapped to . 024 as recommended by eqt who I'm tuned by. No knock, I had brisks and Ruths before, my car didn't really like brisks and Ruths just made it misfire closer to the 5k change out.
Pros: no knock
Cons: caused misfire
Mileage: 5000 km
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
