You're right. The Bosch part # is 80006 on the GP box. I was mistaken. I got them from AutoZone not Pep Boys. It looks like it does have a secondary taper at the tip. Does not say "Duraterm" though. A set of six form the dealer was $87. $48 from AutoZone. They are identical, even the Bosch Box. Don't know why they had them but I noticed they carry alot of Bosche stuff. Nice to know for my MBZ and 911. Buying them was the easy part. Now for the torment of installing them. Well, here goes nothing.
One question. Do the GP #s run from front to back, ie, radiator to firewall or vise-versa ?? Turns out for #3 it doesn't matter.
