Look under the hood, there should be a label telling the correct ones, per the factory production of your engine. It may be on the inside hood lid. I would be interested to know what it says. use those and you can't go wrong. There is nothing wrong with Champion made plugs, if it says those.
the Spec page in your owner's manual should state the OEM plugs and gap. 2.2l subarus LOVE NipponDenso K20PRU-11. Much better than NGK. Now my Yaris 1NZ-FE 1.5l supposedly has NGK Ir plugs. 40k miles in, and haven't thought of touching them. Prob never will. Any driveability problems have been either Gas quality, oil quality or oil filter quality (or all three at once.)
