The vaux twins have a 1mm gap. Haynes specifies 0.8mm i believe.

Not sure who to trust!#

Just to join the club:
LOL @ cybermonkey!

Bosh super 4's come ready set gap

you dont have to gap the plugs as they are a twin electrode on the gsi corsas,my opinion ngk are the best

Tell yah what cybermonkey, if you're so sure about this, open the gap up to about 2mm. Put the plug in with your magic torque wrench and then take it out. Is the gap less than 3mm now!?

wtf cybermonkey lol

I was gonna ask the same thing.....

how does a torq wrench set your spark plug gap????? :lol:

you need a set of feeler gauges mate.

Just keep winding them in until it suddenly gets stiff, then a 1/4 turn. Thats how i do it, and normally equates to about 20nm.

Any other way of doing it ??

As i havent got a tourque wrench and would be tuseday before i could get one from work !!!!

If you go to Halfords and look up your model, the little book on display will tell you exactly the right spark plug to choose. Using the correct torque wrench setting will create the right gap.

you can find the spark plug gap in the back of the handbook you got with the car. If you aint got one ask someone who has. I just had a look for mine but cant find it sorry.

best bet is to look in haynes manual

Nah they come with a 1mm gap and this seems to to too big !!!

the spark plugs should come already coorectly gapped m8 :)
