Just about to change my plugs

Does anyone know for sure the recommended spark plug gap.

Plugs come set at 7mm but I'm sure I have read somewhere that 6mm is the right figure.

More to the point perhaps does 1mm make any difference anyway i.e about a 25th of an inch

0.6

Thanks Ian. Yes of course it is 0.6 not 6mm - I think the heat is getting to me!

Just managed to find the VW instruction manual which came with the van and in the Technical data section it says the following:

Spark plugs for normal operation 2.0 Litre engine

Bosch W8C (Incidentally I have the box in front of me and these come gapped at 0.7mm)
Beru 14-8C
Champion N7

Spark plugs for heavy duty operation (above 25deg C) - you never know

Bosch W7C
Beru 14-7C

Electrode gap (for all the above plugs) (mm) 0.6 to 0.7
