Spark plug Motorcraft or OEM Subaru
Reviews
I have about 30k on my plugs (Motorcraft OE). I've no problem buying them again as they've held up great
Pros: great durability
Mileage: 30000 km
Oem Motorcraft plugs are always my go-to. They generally last around 80k miles.
Pros: last around 80k miles
Vehicle:
Ford
Mileage: 80000 km
Modern Ford engines tend to work best with Motorcraft or NGK spark plugs.
Pros: works best
Vehicle:
Ford
Motorcraft is all I use , heard to many stories about aftermarket plugs causing misfires
Cons: aftermarket plugs causing misfires
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
im at 95k with the original plugs. no issues
Pros: no issues, lasted 95k miles
Mileage: 152887 km
I waited till like 100k to do my spark plugs on my 2013 Crosstrek, they were still good just not as efficient
Pros: lasted 100k miles, still good
Cons: less efficient at high mileage
Vehicle:
Subaru
Mileage: 160934 km
Has anyone tried the Motorcraft SP594 plugs? They supercede from the SP542, which is said to be a 1 step colder plug for our cars. Currently running NGK 6510s but i think i got a "fake" set as i paid like $30 from Amazon for them. The SP594s I can get for $41 from Ford... so anyone have good results?
Part number: SP594
Good luck doing spark plugs
Cons: difficult to replace
Vehicle:
Subaru
That's better than the Motorcraft plugs I received from Rockauto. They were bouncing around (no longer in their original little boxes) in a large shipping box with 2 sets of brake pads.
Cons: bouncing around in box
