There's numerous ones that would be fine. Both NGK and Denso offer several that are equal to or a step up from the ones you mentioned. Plugs are factory gapped and not recommended that you gap them.
Also I noticed there are different plugs based on which type or rear brakes your car has, disc vs drum. Not sure what thats about. Take a look on Rock Auto, at least it's good for comparison purposes. Don't take a chance with Amazon or Ebay, too many counterfeits.
