Im doing a few things to my VU SS before rego check and was about to buy some leads and plugs but was unsure of a good lead diameter and brand 10mm, 9mm?? not sure... Also a good brand of plugs including gap 15mm,13mm??? Any advice?
I wouldn't recommend the Bosch lead sets I brought one and no matter what order I swapped them round I always ended up with one lead extremely tight
Stick to genuine or standard aftermarket replacement leads and renew them often, every 12 months or so is good if you like your car to be kept running at its best. Cars these days seem to go through plug leads fairly quickly because of the very high voltages EFI systems run at. Definitely not like years ago with the old points systems where a set of plug leads could last for years in some cases. Even the more expensive 8,9 or 10 mm leads wear out just as quick as the standard ones. I find that after 12 months or so, plug leads start to loose their edge and will slowly start to effect the fuel economy and running ,starting etc.
