2.8 spark plugs

[Davyhoogy]

So my car came with a new set of plugs and filters. Random buts n bobs.
Looking at the plugs I have here I don't think they aren't the right ones for the car.
Which also worries me they aren't correct that are in thd car, which could explain dodgy starting.
Not sure i trust my findings online either so can anyone clarify which ones are standard and if it's worth getting the upgraded ones, if any.
2.8 1998

The spares I have here are BOSCHE FR7LDC+ 7402+7
Eurocarparts says these are incorrect but has about 8 different options to buy
