Just a funny note-I work for a Chevrolet dealer in town and ordered spark plugs for a 1999 Catera. They came in an AC Delco box-but inside were 8 individual boxes with opel logos on them-thought that was neat-they are linked with german parts pretty well. They are boshe 3 prong platinum plugs- and appear they would work for the Opel GT-will compare later- only problem-$11.00 retail

What about the four "extra" ones that somebody ordered because they thought the Catera had a V12 motor???

I looked when Bosch first introduced the Platinum-Plus4 plugs, but as far as I have been able to determine, there are NO Platinum-Plus# plugs (2-, 3- or 4-prong) available with a .460" thread reach required for all CIH heads, except early '68 1.5 heads!

Seeing that the Cat has a V6.....there's going to be a bunch of spare plugs around!!!
