67RCE, I may be wrong but I thought you could use the other leads as the plugs are the same, the packs just come with the extra lead for the coil? Dunno, havent tried it but thats what I've been told.

Bosch leads are the go buddy, $50 thereabouts for standard ones and you're onto a winner. If you want some 'bling' you can splurge the extra 30 odd for the fatter blue ones. But I'd change plugs as well as suggested for sure, you'd be mad not to.

I'm not sure on EF, but I know the AU leads I've looked at have clips to locate them on the Coilpacks....

Yeh maybe, I've never taken any notice. EF & AU1 use the same coilpack, but the EF run longer leads. I'd buy AU1 leads as I really dont like how all the EF leads run across the top of the exhaust side.... I'd say lead 1 would die fairly often from being cooked. Plus AU1 leads look neater coming across the rocker cover anyway.

my ef ones are just standard boring old leafds no fancy clips swing lit on the devils dance floor
