Thanks very much ! That's not much torque, a lot of potencial to over torque them and sure then you need good luck !

The current ones are in from factory so I asume they are torqued right

Snug is my torque spec.

Its hard to get a torque wrench in tight areas for spark plug tightening, so I generally go by feel.  When you are loosening them, keep a mental note of the pressure you applied to loosen them then try to snug up the new ones as close as possible.  Its not very scientific I know, but I've changed A LOT of spark plugs over the years and I have never had an issue with over tightening them or having any get loose.

Thanks to all for there advices.

Saturday I found the time to change the oil, filters, spark plugs and spark wires ( the first owner had a Marten living under the hood )

Other than I feelt like I'm in Gullivers travels LOL I have to say I had real good access to all the parts which I changed !

If I had liked I could had used a torque wrench for the spark plugs because there was enough space
