Volvo OEM Spark plug wires are Class "F". Aftermarket Spark Plug wires are Class "E". Both are made by Bougicord.
The FAQ references Class F as 180 degrees C and Class E as 160 degrees.
My question is are you running Class E or F? Is there a benefit (perhaps longterm durability) in purchasing Class F rather than E?
Also, my '89 760T has a Class "C" coil wire. The previous wire was affected by temp and the insulation was worn (where it was against a ground strap from valve cover). Should the coil wire also be class E or F?
Thanks!
