Spark plug BRISK or OEM Mazda
I switched to brisk just because of the high amount of ngk knock offs and they are supposed to last a bit longer and or have less wear than the ngk I'm a step colder rr4ys they have been great.
Pros: great, supposed to last longer
Cons: high amount of knock offs
My RX8 also got pretty piss poor compression numbers. The only time it struggled with a start up was with literally the original 20 years old plugs it came with and I had to do multiple hot starts. It still started and carried on.
Pros: still started and carried
Cons: piss poor compression numbers

Mileage: 30000 km
At around 120,000 KM plan for spark plugs. It's easy, especially if you get a 1/4" torque wrench and 14mm 1/4 deep well socket.
Pros: easy to replace
Vehicle:
Mazda 3
Mileage: 120000 km
You get a better performance if you install a booster plug, DNA air filter and Brisk spark plugs. Great torque from 2000 rpm as a result.
Pros: great torque from 2000rpm

I bought a 19’ Premium at 17 it’s a great little car beat the shit out of it for 4 years straight and it runs amazing still. Handles well in the winter as long as you have clearance it’ll get you there in one piece. Regular maintenance along with trans fluid change, spark plugs, brakes, diff fluid change. I’d recommend a cpo premium . Great value.
Pros: runs amazing, handles well
Vehicle:
Mazda 3
I would recommend that if you get one do a full service fluid change on everything. Change the coolant, the trans fluid, diff fluid, oil (10w30 or 10w40, do NOT use the 5w20 reccomended). You'll also want to set aside $80-90 for new spark plugs, and upgrade the coil packs to LS coils from Bennet Built whenever you can. Coils need to be replaced about every 30k miles.
Pros: strong rotary, mechanically inclined
Cons: everything is breaking, plastics dry
Vehicle:
Mazda
Mileage: 73000 km
Right before i changed the map I also swapped spark plugs (brisk er12s). Since it started the rough vibrating, I’ve inspected spark plugs and coil packs, changed the coil pack grounding to a ground kit, cleaned the MAP sensor, and even tried throwing some liquimoly valve clean in it.
Cons: rough vibrating

Volkswagen
Mileage: 112000 km
Part number: ER12S
Brisk are fine. You have to check them about every 5,000 miles. And change out sooner than other brands.
Pros: are fine
Cons: check every 5,000 miles
Mileage: 5000 km
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+.
Pros: NGKs last longer
Cons: Brisk wears quickly
Mileage: 10000 km
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.
Cons: susceptible to fouling up
