Correct torque setting for spark plugs?

[CuppyDean]

Hi guys,
Read a few post and is it correct the spark plugs on the 172 should be torqued to 25nm? im looking at a spark plug preset wrench on ebay which has a set torque of 24nm, will the 1nm make any difference?

Cheers
Dean

dont worry too much, when they start to go tight just go 1/4 of a turn, if your that hell bent on a torque setting 24/25 is fine.

They need to be torqued properly for cooling and heating apparently.

25nm is right I think

Yeah 25nm is right, just wondered if the other 1nm would make any difference

1Nm is barely notable for sparkplugs. The range is 24-29

Thanks for clearing that up

ive saw people do this, unfortunately ive then had to put it right when its blew plug number 3 out the head.

service cars day in day out not one come back, you can only go so tight with a spark plug anyway, unless your a muppet and keep tightening it, have heard of a few 172's doing this on the forum though.
