What if it doesn't fit?

We back every order with a fits-guarantee. If a part doesn't fit your specific Subaru Outback despite matching the listed fitment, we accept returns and exchanges within 30 days. Always confirm by VIN before opening packaging if you're unsure.

Should I use OEM or aftermarket spark plugs?

Both are valid. OEM provides factory-exact fit and standard warranty support. Premium aftermarket from Bosch, Denso, Gates or ACDelco often matches or exceeds OE performance at a lower price (they make the parts that GM/Ford/Toyota sell as OEM). Avoid budget aftermarket for safety-critical parts.
