OEM Subaru › Spark plug

Starting:

The most expensive proposition was a new windshield, but your particular insurance could solve that. Spark plug replacement was a surprise as far as cost is concerned. I've routinely changed the oil and cvt fluid once. No other maintenance issues. I love the car. Incredible roominess in the cabin and very capable offroad when needed.

Pros: no other maintenance issues, capable offroad

Cons: expensive windshield, costly spark plug replacement

Vehicle: Subaru Forester

Mileage: 98000 km

I now dread doing spark plugs. Something that’s super easy to do on most 4 cyl cars is a PITA doing on my ej25.

Cons: spark plugs difficult to replace

My 2015 outback has 140k miles. I just did spark plugs and belt, brakes. That's the only maintenance I've ever done other than tires and batteries.

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

Acceleration:

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
