changing spark plugs on a 2014 Mazda 3 2.0L iSport

Описание: Coils - 8mm - 6-8 ft lbs
Spark plugs - 14mm spark plug socket (and a medium extension) - 12-14 ft lbs
I found the service manual here: https://www.mazda3revolution.com/thre...
Oil on the spark plug is NBD - the little metal ring they come with is a new gasket, so you're already addressing the issue.
