Iltis plug
Hi
Thanks Dave for the info. Does anyone know the Autolite cross reference for the Bosch WC7D? Thanks Dan |

I do not believe there is one that crosses over to the Bosch plug. As far as I know the Bosch plug is the only plug made to fit the iltis with the deep reach threads for the VW head. If there is an equivalent plug out there it would be great as the Bosch plugs are hard and expensive to fine here in Canada.

Just looked in the NGK book for a cross reference, but I can't find a WC7D. They cross reference Bosch W7D and a WR7D, but that's as close as it gets. Does anybody know what the "C" in WC7D means? Obviously the W7D is non-resistor type and WR7D is resistor type, but what is a WC7D? Copper core? Any Bosch plug experts out there?

There was a point in time around 1989 when we could not get the original Bosch spark plugs and in an emergency would use the old SMP spark plug like the 2243. Despite the short reach they worked, however we changed them back over to the Bosch as soon as new stock was received.
I just had a look at Rock auto in the US: the Bosch plugs are available there but at a cost of around $25 a plug. Wow. |
