Subaru Legacy Spark Plug

Your mid-sized Subaru Legacy is a reliable ride that ensures top-notch safety whenever you hit the road. Make sure that your vehicle lives up to its name by upgrading from factory spark plugs to AutoZone's performance spark plugs for Subaru Legacy.

Spark plugs are just one of many essentials your vehicle needs to start and maintain its good performance and lifespan. When the plugs on your vehicle start to go bad, your Legacy's performance easily falters. If your spark plugs get too hot, they could ignite the fuel before the spark fires, so it's important to invest in the right type of plug for your make and model. Order your new Subaru Legacy spark plug set from AutoZone and enjoy home shipping. Or, drop by your local store and benefit from free battery charging and engine diagnostic testing while you shop our unbeatable line-up.

      My 2000 Subaru legacy Gt with 250,000 miles and I drove from PA. To Nevada . My gas mileage was 28 miles a gallon where it generally would get no more than 25 miles.

      The gaps were not consistent oddly. Had to adjust 3 out of the 6. Changing plugs on a 5th gen Legacy with the H6 motor is an absolute nightmare, but the originals from 2012 with only 20k miles were still in the car and the idle hunted around a lot and was high when cold starting. New plugs fixed all those issues. Good for another 10 years and 20k miles.
