Are they Bosches?

Yes. They are Bosch 4417 platinum +4. They were run in my 2.5L and pulled after 30k

miles @ 110k on the engine. Also for convenience you do not gap the plugs, just inspect

the electrodes for damage before installation.

Great plugs but good luck finding those, or any Bosch Platinums, for any vintage car. Bosch has gone NLA for older cars which is a shame.

Not a fan of NGK or most Japanese parts but these days there are no German counterparts (Thanks Bosch!). Yes, I know the OEM plugs are Bosch but to me those are 70's technology.

It's so strange that in modern times, our selection is so limited. It used to be that there were so many spark plug choices for any car but nowadays, not so much.
