top gun leads.

[SUSS]

hey guys just quik question.
do you guys reckon 10mm leads are too big? i got series 2 vn v6 manual.
should i put 8mm or 10mm? and also wot spark plugs would be best?
thx.

I would look into Magnacore leads. I got Top Gun leads and wasnt very happy with them.

Spark plugs, I use NGK Iridium IX's. They're more expensive but they last alot longer and they make a difference. It idles alot nicer now.

10mm is a waste of money I have been told unless you plan to pull massive revs out of it.

Like well over 9,000rpm.

One of the companies we deal with at work (Very big performance wholesaler) doesnt recommend them unless you are doing this sort of thing to your engine.

I have sold hundreds of sets of Top Gun leads and never had a hassle with them and only one or two sets come back due to people doing stupid things with them
ie: one clown bought some back saying they had melted and further inspection and questioning revealed they had been sitting on his bench in a pool of brake fluid the night he fitted them.

By the time he got 200 clicks from town they had disintegrated enough to short on the manifold hehe.

If your rich tho go hard.
But yeh I can think of a lot better things to spend the extra dosh on personally.

Top Gun leads are no better than standard leads, people who spend extra on them (like I did) are just wasting their money.

The only reason places like Repco etc. reccomend them is because a.) they don't sell anything better such as magnacore and b.) they probably don't know themselves.

I have been running 10mm for over 12 months maybe longer easy on the VP,, Never had an issue don't see the need to change them at all soon.
At first when changing them i felt they offered slightly faster responsiveness to input.

And normally i change leads twice a year, So they might have costed more but they last 4 times as long.
That with Iridium plugs perfect deal.

[1991_Vn2nV]

I dont see why you would need to change leads twice a year man.

That guy selling the FX for 1.2million, it has the original leads on it. 60 years old! And she still runs lol

[crazywog]

i use bosch and ive tried top gun and i find no diffrence with them the oly diffrence ive been told is that u can bend them or tie them in a knot and they wont break like stock leads all crumble up so id say just go with the normal 8mm. anything else is for those of u running turbocharged or supercharged engined is perfect i got told by rajab and bresciani they said go with the normal 8mm i dunno wat to say depends wat ur running?

[vxcalais_01]

The Top Gun 8mm Max 300 Leads are meant to be the good ones, lead cable made in USA.

But if you really wont to keep it efficient running perfect it doesn't hurt to change these things like oil a few times of the year.

You could have bought my mums old VB with factory oil for $30.

[daron]

ive had 5 diferent sets of leads 10mm top guns were the best never had a problem now i run msd leads
all made to suit my mods not stock factory leads

[tanka5.7]

i got 9.5mm procomp leads off ebay for 45 bucks and im quite happy with them

[KRUPTD]

On a standard ignition/spark system there is no need to run big spark leads the biggest would be 8.8mm or 8 mm,i swear by bosch they make good plugs and leads and other ignition parts.I have seen some 500hp commodores and falcons running modified ignition systems and only running 8.8mm ignition leads and they have no dramas whatso ever.Remember bigger isnt always better.

[Full Spectrum]

It's not that there bigger, There a better design stronger longer lasting with less issues with them..
I'm going to leave them indefinitely with the iridium's and have a good tune for it. Then see how good it's runs for the next 12 months only changing oil.

With the Iridium IX plugs if thats the ones you are running, i've had those in my VN for ~60,000km's now and they're still working like a charm.

They are beauty's And that proves it..
Well worth the extra $60.

I'm not sure i know how long i have had them in for?? Maybe the time i lowered the car back in june 06?. But i haven't done that many km's.

[coolvxss]

How long do leads last. Surly you dont have to change them every year?? Ive had my car for 3 years and done about 60 000km and havnt changed them, and who knows how long they were on my car before i bought it because i have never changed them. How do you know when they are due for a change? my car still seems to be running fine. And how long in between spark plug changes? I changed mine about 30 000km ago.

[vn calais manual]

shed be due for one now id say.

[coolvxss]

How many kms do plugs and leads usually last?

[1991_Vn2nV]

Stock spark plugs I wouldnt leave in longer than 10,000km's.

[Full Spectrum]

Stock are cheap so twice a year i get around 20,000km driving.. And as cheap as they are it doesn't matter, Like oil i change every 4 months it does get out to 6 months sometimes Lazy., Some say I'm mad and i am.. But i feel the car runs much smoother with fresh oil and it seems to love it and keeps running like a dream never missing a beat in it's old age.

But out lay a touch more for plugs leads air filter a longer lasting higher performence..
$100-$120 Plugs.
$100-$120 Leads.
$80 K@N air filter..

Think of the money you will save, Plugs and leads go for 5-6 times longer, And the Filter is reusable..

[calaiscruzer]

I had top gun leads in my car, were average. Got genuine holden ones now and they seem to go much better, mind you the top guns were probably 2years old, but i did clean them often.

[Emackulation]

Dylan, these magnacore leads, who makes them? never herd of them before. Got me interested. I to have had top guns, dont see the big hype.

All, other things being equal, the difference b/w the 8mm and 10mm leads is 2mm of insulation. This just makes them more suitable for higher energy ignition systems where the chances of spark leakage through a lead will increase. There is no such thing as a perfect insulator, just the extent to which the will conduct. Again, all other things being equal, the performance from a 10mm lead and an 8mm lead will be exactly the same on a standard energy ignition system........there is nothing to gain by taking off the 10mm leads and replacing them with the 8mms.

[calaiscruzer]

AAh, so just the insulation is thicker, id didnt even think of that. i would have thought the core was thicker also?
Well then if i wanted thicker leads, i wouldn't spend $100+ on a set, id just wrap them in electrical tape..lol

[commsirac]

The more expensive sets provide better cores as well, as I said, "all other things being equal" , however, the overall diameter of the lead is due to insulation.
Definitely I think there is an assumption that the thicker leads carry more electricity/power etc, give more spark to the motor, no its not the case.
Actual current flowing through the wires is relatively small.
