Bosch Platinum plugs

I run the bosch platinums with a msd 6al and haven't had a problem in years
Im keeping the Boschs just incase Im sure there is really nothing seriously wrong with them,its just Ive pretty much replaced everything on the motor since installing it(like new oil,oil filter,fuel filter,dist.cap & rotor etc),might as well put fresh plugs and wires.Besides,I have no clue as to how old these plugs are.:profilel:
