Beck/Arnley Direct Ignition Coil P/N:178-8527
Beck/Arnley 178-8612 direct ignition coil for the 2020-2025 Subaru Outback H4 2.5L and other vehicles turns battery voltage into the high voltage a spark plug needs. It is application specific and matches OE form, fit and function.
A misfire, a rough idle or a check engine light can mean a coil has weakened. These signs alone do not prove the coil is at fault, since a worn spark plug is another common cause.
The same coil fits the 2020-2025 Subaru Legacy H4 2.5L and the 2024-2025 Subaru Crosstrek H4 2.5L. These H4 2.5L engines take four coils, one per cylinder, and this listing is a single coil.
