Maybe. Look at them-- black wet? Clean or replace. Gold color? Leave in, check gap. I ran 5 year old gas thru my Honda, ran fine.
Nothing Wrong with Champions. My Harley specifies them or "Harley" brand,which are Rebadged Champ and $$,. it's either these or $16 Pt. The dealer looked at my Champs, said she's Fine.Went 280 miles to Mormon Lake (7,000 feet), never missed a beat. About same mileage to Rocky point, still ran fine on that crappy lo octane Mex gas.
If you have a Jap vehicle, use ND or NGK plugs; German, Bosch; American, Champ or AC. A Real mechanic, not an avatar on YA, told me this, something about tolerances. And, karma, I guess..
