I need to replace the leads on my VR v6, it is a bit worked with a big cam, ported and polished heads etc, Im not sure what brand is the better and what size should I go for 8mm, 8.8mm? Any suggestions would be great
Unless you are running forced induction or really stupid high compression, a lead is a lead. Doesn't matter what you use.
As above, stock leads would be fine. I alway use genuine Holden. Not much dearer than aftermarket and come with new metal ends.
Thanks for that, was thinking of going for a set of TopGun 8mm leads with the heat sheilds, around $85 from local Autopro.
I've always used Bosch performance leads and have found them to be reliable. Also, I think there may be a little to gain by using performance plugs such as Bosch super 4's. Maybe those iridium type might be okay. I know they're much longer lasting than standard ones.
Don't bother with Magnecor either, they are supposed to be good for hi temperature, but i managed to melt the boots on track day. Genuine are good leads mate, and the heat sheilds actually fit properly so they last for ages.
Cheers for that, I got some TopGun 8mm leads with new heat shields as well, the old ones didn't have heat shields on them at all, seems to have made a difference its idling a bit smoother, plugs where changed not long ago ( 1 month ) so left them in. Still need to look at the oxygen sensor yet.
i have top gun 10mm leads and they work a beauty around 120$ and they just give really good throttle response and somewhat better fuel economy
I wasnt sure about the 10mm ones, thought they might have been to big, but the 8mm seem to be ok, my motor is worked a bit and perhaps should have gone bigger leads.
