vs
Spark plug BERU or OEM Mazda
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
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
Vehicle:
Mazda
Mileage: 73000 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
Had these Beru plugs put in last year. Are they the kind that’s at greater risk for damaging the engine?
Cons: risk for damaging engine
