Spark plug leads

[tezza]

Hi everyone,

Well the ute is misfiring underload, so Im going to change the spark plugs and leads in it.
One of the leads got damaged as I was pulling by the cord instead of the head of the lead (whoops).

Question is, are genuine leads better or just use some Bosch or Top Gun ones?

Thanks

I just used Bosch as they were the cheapest and they are pretty good quality. It's debatable whether expensive ones work any better.

The main thing is replacing them regularly as the voltages they carry these days is very high with EFI,so they dont last very long anyway compared to how long they'd last years ago with the old points systems..a set of leads would last for years back then..I replace mine on my VS every 12 months.

I think I paid $60 for a set of eagle 8mm. They are probably the most highly recommended aftermarket ones. Its just the insulation thats a bit thicker, not the actual core itself. If your leads are rooted any new set will do the job though.

i swapped my stock leads n spark plugs for Top Gun leads and NGK spark plugs, n saw a great difference

i believe that genuine leads are heaps better than top gun but i guess it's like everything else, there are lots of different opinions.all i know for sure is that i tried top gun leads a couple of years ago and they were breaking down after 50,000km.i usually change my genuine leads every 80,000km which is before i notice them breaking down.as far as plugs go.genuine or ngk,i can't complain about either. don't overlook the possibility that your coil pack could also need replacing.good luck.

Genuines the way to go.

Will check out some prices for leads at Repco and Supercheap tomorrow.
There is a full service kit and all on Ebay with genuine leads for a pretty good price, although I'd like the car running again this weekend.

How do you know or how can I test the coilpack?

Check the primary resistance 0.3 - 1.5 and secondary resistance 5 - 7 kohms.
