Spark Plugs

Subaru Spark Plug Care and Maintenance 101

The engine in your Subaru has begun misfiring, or worse, it's failed. You've ruled out a bad starter, alternator failure, and some other part of the engine being faulty. Now, you've figured out the real problem -- a defective spark plug.

Luckily, whether you're driving a car like Subaru Legacy, an SUV like Subaru Outback, or otherwise, replacing spark plugs is easy, though if you're not sure what to do, the pros at a Subaru service center can help.

After that, all you'll need to do to help the plugs last as long as they can is give them a good regular cleaning. There are five easy steps to that.

1. Using a spark plug socket wrench, disconnect each plug from its lead.
2. Clean off any dirt or debris around them (you can use a can of compressed air if you prefer).
3. Use fine-grit sandpaper to wipe off each of their firing ends/electrodes.
4. Scrub their threads with a wire brush.
5. Replace the plugs.

You can also spray the plugs with brake cleaner if you want to; just wipe them off afterward.
