Spark plug OEM Mazda or OEM Subaru
Reviews
Subaru forester. Mine is a 15. Comfortable, decent gas mileage, able to seat 4 with stuff in back. Kayaks fit on roof. AWD helps in rain and snow. Easy to do basic maintenance, but spark plugs SUCK.
Pros: comfortable, decent gas mileage
Cons: spark plugs SUCK
Vehicle:
Subaru Forester
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
I just changed the spark plugs for the first time in like 175, 000 miles
Pros: excellent longevity
Vehicle:
Mazda
Mileage: 281624 km
So I decided to I replaced my spark plugs. There was a ton of carbon build up in the first cylinder, and oil on the 2nd, 3rd and 4th spark cylinders, including the spark plugs. It’s running way smoother now but there is still some jerking but it’s not as violent as before.
Pros: running way smoother
Cons: still some jerking
Vehicle:
Mazda 2
Changing my sparkplugs for the first time (32k miles, yes it's early but I got a great deal on the plugs) and found that the stock plug in cylinder 4 actually had a ground electrode defect and was significantly thicker than normal. The car runs stronger than it ever has as this was likely causing extra timing pull.
Pros: car runs stronger
Cons: ground electrode defect
Vehicle:
Subaru
Mileage: 51500 km
We just got the 60k service done (spark plugs) and it still does it.
Cons: shaking still present
Vehicle:
Subaru Outback
Mileage: 96560 km
Good luck doing spark plugs
Cons: difficult to replace
Vehicle:
Subaru

Cons: spark plug job difficult
Vehicle:
