You know how difficult it is to find spark plug wires for our cars. Has anyone replaced the stock wires with aftermarket wires succesfully ? If not, my idea is to get a group together & contact BEHR who originally made these for Ferrari and place a large order w BEHR for a new run of wires. Whos in ? I will order 6 sets myself
http://www.kingsborne.com/html/ferrari.pdf Not only will Kingsborne custom make your 512 spark plug wires, but they'll wrap them in 1200 degree color coordinated external sleeves. http://www.kingsborne.com/insulatorsleeves.htm
Just FYI, if you call Magnecor they'll make you any set of wires you want. When I switched the 308 to EFI they made a custom set for me. I measured because I needed a different length than stock, and then just had to swap the extenders over. Although, if you are just looking for OEM replacements, you could just send your old wires to them to match, and I bet they would swap the extenders over for you. IMO, they're the best you can buy, and have quick turn around as they generally cater to race engine builders, etc. http://www.magnecor.com/ They have the TR listed, that was the only 12 cylinder I saw glancing through the online catalog. $170 if you reuse the stock boot and extender.
