Spark plug Motorcraft or OEM Subaru
Reviews
Just traded in my 2015 Forester with 219,000 miles and the original spark plugs.
Pros: lasted 219,000 miles
Vehicle:
Subaru Forester
Mileage: 352445 km
I do run Motorcraft plugs because they seem to crack a little less than the Autolites.
Pros: less cracking than Autolites
anecdotally, my truck was at 226k when i changed the plugs. motor craft plugs coated, no anti seize, torqued tighter than advised. probably 20lb ft. 2 rear plugs were originals. i’m now at 235k and nothing wrong yet.
Pros: nothing wrong yet
Mileage: 235000 km
I’ve found that Motorcraft platinum spark plugs work best in my 1998 Ford Ranger. I tried Bosch plugs and it ran terribly. Nothing but Motorcraft from now on (for Fords).
Pros: works best in Ford
Cons: Bosch plugs ran terribly
Vehicle:
Ford Ranger
I however replaced mine with motorcraft and do not have pinging anymore but still run 91 octane as 93 isn’t common in socal.
Pros: no pinging anymore
Normally that's a result of a failed spark plug seal. If you have no other problems I would put new spark plugs in it and check them at the next oil change.
Vehicle:
Subaru Impreza
On any of the gas trucks with the "modular" engine family (4.2 V-6 and 4.6/5.4 V-8) it seems like if you use anything other than Motorcraft spark plugs and coil packs, the engine won't run right at all, no matter the brand.
Cons: engine won't run right
Vehicle:
Ford
We just got the 60k service done (spark plugs) and it still does it.
Cons: shaking still present
Vehicle:
Subaru Outback
Mileage: 96560 km
Iridium plugs suck on fords.
Cons: suck on fords
Vehicle:
Ford
a spark plug job on an STI can be a 6+ hour job :thumbdown:
Cons: spark plug job difficult
Vehicle:
