vs
Spark plug OEM Mazda or OEM Volkswagen
Reviews
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
Vehicle:
Mazda
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
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

I just changed my plugs at 75,000 miles...I was impressed as to how clean the plugs were and the color. Looks good. The gap was still .030 as the new ones were (VW 06K905601K). Definitely could have gone much longer but it's an easy replacement.
Pros: clean plugs, good color
I put a new battery in it. Because it needed one but then I changed the spark blood wires and it now acts like a brand new car, so go to your spark plugs first.
Pros: acts like new car
Vehicle:
Volkswagen Jetta
2015 Passat 1.8L TSI 170,00 miles. De-carboned the combustion chambers and cleaned the spark plugs. Resolved slow response to accelerate. No oil consumption after 3k miles so far.
Pros: Resolved slow response
Cons: None
Vehicle:
Volkswagen Passat
Mileage: 170000 km
Ive tried other plugs that are oem spec but not from VW and I like the way the oem plugs work better.
Pros: work better
Vehicle:
Volkswagen Golf
I’ve done an oil change as well as swapping the spark plugs and coils for brand new ones. The roughness persists!
Cons: roughness persists
Vehicle:
Volkswagen Jetta
The factory spark plugs are honestly shit in terms of longevity.
Cons: poor longevity
Vehicle:
Volkswagen
