spark plug leads for LPG (ecotec v6)

[vh-holden]

I got my new car yesterday. It's a vs sii with factory gas.

The previous owner gave me a set of leads he got last week but didn't get a chance to put on.

They are gasmaster brand. The thing that concerns me is that there is no metal sleeve around the plug which is close to the exhaust.

Should i use them or look for something else?

Also, what gap should the plugs be?

Yes i would use the alloy caps around the plugs, the plugs should be one heat range colder than normal, and the gap is 1.5mm.

Just use the old sleeves (which are a bugger to get off). Plugs are supposed to be set at 1.5mm.

quote me if im wrong but my mechanic advised me to gap them at .90mm for gas.....

i had them gapped at 1.5mm and had all sorts of probs with the way it ran..
