my car came with them initially, does anybody else still have them on theirs...? just wondering..

Are you talking about the metal surrounding on the three spark plugs on the side facing the rear? If so, then yes I still have mine on.

i had 6...

3 here, on the back three plugs.

yup 2 on mine I think it had three. I also add heat shields/boots to all my plugs

TY

I've got 3 facing the firewall.

I think the back 3 towards the firewall are the only ones I've got too.. although I might have them on all 6. Been a while since I've changed the wires
