[hold-on]

I have a series II VS ecotec, I want to change the spark plugs, can anyone recomend a good brand at a good price???? and also whats is the correct gap 1.5mm?????? and is it an easy task, never done it b4

NGK about 4 dollars a plug, dont worry about the gap, as they are set when you buy them, autobarn/supercheap etc look in there book, and all done, u mite wonna buy a psark plug remover socket or device too

I would worry about the gap, just check it regardless. Even though they're supposed to be gapped from factory, there are times when they're not. Buy the tool to remove them, very simple from then on.

When putting plugs in, as soon as you feel it hit the head, another 1/4 turn and thats it.

And pull the plug leads off by grasping and twisting the plug cover NOT the lead as you will break it. They can be a pain to remove from the spark plug.

Also, I've found that removing the airbox piping between the throttle body and air flow sensor helps, as it gives a bit more room to work in. The driver's side isn't too bad, although the ABS modulator gets in the way a bit, but you just have to be patient...

The tools I used were...

Half inch socket set with the correct plug socket, short extension for the passenger side....and balljoint extension for the drivers side....when tightning I get them firm then nip them an extra 1/8th of a turn.

I think the most awkward plugs are the drivers side as you've got the heater hoses and switch to avoid aswell as abs gear if you've got that fitted.

Also degrease around the plugs with a spray on degresser and hose off before removing the plugs to avoid any built up crap around the plugs falling into the motor...and if your memory aint so good only do one plug at a time to avoid mixing up your plug leads and cylinders....

The genuine Holden plugs are the cheapest and the best (they are almost the same as NGK plugs). The gap is already done for you at 1.5mm.

I use the Nippon Denso plugs available from Toyota(for lexcen), i find they work better and last longer than the GM ones, they are about $3.60-$4(got mine for $22 a set)depending on dealer, i just did mine on w/e , had bosch super in b4, they worked pretty good, but getting bit old now, just remember the right order of ur leads and ull b right, i got mine set to 1.5 as specified on the left strut tower and by Nippon Denso for my engine


also be careful putting new ones in not to cross-thread the hole in the block(very $$$ to repair), and not to bend the plug or crack the white ceramic insulator as i leant the hard way, did that in the vp , started it up , was missfiring, backfiring, drove like **** but had to buy a new plug , all because i bent the bit that connects to the leads on one plug
