914World.com _ 914World Garage _ NOS Bosch Spark Plug Help

Posted by: Nogoodwithusernames Nov 9 2021, 03:36 PM

Hey all, I was given a pack of old Bosch spark plugs that I haven't been able to find a ton of info on.
The number is W230T30 and they look like 14mm x 3/4" that would fit in the 914 but not sure about heat range or anything like that.
Anyone seen these before?

Even if I can't use them they are pretty neat, haven't seen spark plugs wrapped in wax paper before so that may tell you how old they are? And how young I am maybe?
