Spark plug OEM BMW or OEM Mazda
I did absolutely nothing apart of spark plugs and oil change . I had E90, 188k km, 330d until it meet it's end when I crash it to railguards. it never showed me any lights or anything so I would say around 60-80$ tops.
Pros: reliable, no warning lights
Vehicle:
BMW
Mileage: 188000 km
I almost went 200000 km on my bmw between spark plug changes, and the motor runs so much better after. My fuel economy almost doubled, and performance was a night and day difference
Pros: motor runs better, fuel economy doubled
Vehicle:
BMW
Mileage: 200000 km
Just did mine at 69k. Felt like a small pickup in performance.
Pros: pickup in performance
Vehicle:
Mazda
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
Spark plugs, coolant exchange, transmission drain/fill, brake fluid flush, and air filter replacement, stat.
Vehicle:
Mazda 6
I did my spark plugs on my 335i f30 and I can say one thing. $400 for labor on spark plugs is treason. Shit should take those "experienced" mechanics maybe an hour.
Cons: expensive labor
Vehicle:
BMW
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 dug factory installed spark plugs out of my recently departed E90... they looked like something from the stone age. 19 year old car, and from what I could tell, never had the plugs changes.
Cons: old spark plugs
Vehicle:
BMW
Cylinders 1-3 were misfiring. They couldn't get the spark plug out of cylinder 3 because the other dealership had over tightened it. They had to get a special tool to remove it. The tool BROKE because apparently it was so overtightened and mis-threaded. They finally got it out yesterday and sent the cylinder to the machine shop to get the head off. I just got word that there is a hole in the piston and the valve head is completely gone. They are saying now that it has nothing to do with the spark plug being overtightened. He asked about driving through water, and road conditions. It was a dry day. Not an issue. They said I need a new motor at this point.
Pros: spark plug removed, new motor needed
Cons: overtightened spark plug, broken tool, hole in piston, valve head gone
Vehicle:
BMW M4
Mileage: 23800 km
