8mm or 8.5mm Magnecor HT Leads

[Matt_Clio172]

Ordering a set of Magnecor leads on wednesday. Had a huge missfire, which turnned out too be the coilpack. Changed the plugs at the same time too. However I still have a very slight missfire in low revs now and again. So I am changing them.

Just wondering is it the 8mm leads I will need or the 8.5?

I have done a search but couldn't find anything.

i think 8mm on std cars and i think i read if your cars moddded (i mean more than filter and exhaust) then 8.5mm are better.

Won't make any difference, do you want red or blue basically.
