Why Replace the Coil?
Old ignition coils:
- Break down from engine heat
- Develop weak spark output
- Cause intermittent misfires
A fresh coil restores proper ignition energy and reliability—especially on aging boxer engines.
Installation Notes
- Direct bolt-on replacement
- Basic hand tools required
- Recommended to inspect spark plugs during installation
(Subaru spark plug access still remains a test of patience and wrist flexibility.)

No giant horsepower gains.
But fixing misfires and restoring smooth operation makes your Subaru dramatically better to drive—and you’ll notice it immediately.
