Spark plug OEM FORD or OEM Subaru

I waited till like 100k to do my spark plugs on my 2013 Crosstrek, they were still good just not as efficient

Just traded in my 2015 Forester with 219,000 miles and the original spark plugs.

Had to replace the plugs and ignition coils last summer and that fixed it.

My 2000 Ford Ranger with a 4-cylinder and manual is just about the simplest vehicle that could exist. SOHC engine, so not much that can go wrong in it. It's very satisfying to work on because you don't experience the shitty feeling of knowing you spent way longer on something than it should have taken.

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.

Until I replaced the plugs, coils, alternator, starter, battery and cleaned connections all I could, this problem persisted and my vehicle killed a coil / 2 every season.

2005 CVPI...180,000 mi....spark plug blown out of head. The Crown Vic was purchased at auction for $4200 a bunch of years ago with 100,000 miles and was very good to us until about a week ago...original engine, suspension parts, transmission and very few repairs.

I own one of these, and I couldn't have a lower opinion of Fords engineering (the 2v spits out spark plugs? lets "fix" it on the 3v and make it so they will never come out).

a spark plug job on an STI can be a 6+ hour job :thumbdown:

econolines are ok except for one huge cluster****. On the late 90s through 02 i think they built them with too few threads on the heads for the spark plugs. Consequently spark plugs routinely blow out.
