Yes they can
i can vouch for this first hand. i installed autolite 25 in my truck ( from autozone , had the guy look em up and hand em to me ) they are "supposed" to work with my engine , came pre gapped and everything. i double triple checked the gap on every plug and installed them. upon engine turnover the engine shook in a severe fashion and was misfiring on almost every cylinder. i returned the autolite plugs and got the factory installed plugs ( 10 cents more each lolol) installed those plugs and the shakes were instantly gone.
first hand experience, can u ask for anything more.
