2014 Subaru Crosstrek: replace all 4 ignition coils or just 2? (4-cylinder FB20b)

ctjfdB to Mechanic Advice@gearhead.townEnglish · 10 months ago

Currently sitting at the dealer for a visit that was initially for CVT issues (none were found).

Misfires in cylinder 1 and 3.
I’m really close to that 60k mark so I’m going to change the spark plugs (at home), but they are also recommending replacing ignition coils #1 and #3. Figured I might as well do that while I’m in there.

My questions is should I replace all ignition coils as a set? or will I be fine in the long-term just replacing #1 and #3?
