The recommended torque does not index your plugs do it the old fashion way, they are warrentied for 3yrs, and you should not have to replace them yet. The reason for the indexing and the tolerance is 90 deg inline with the injector is to insure the 1st pull start, nothing more, if the indexing is off than the sled may have to be pulled more than once to start it.
I have replaced mine last year chasing a hesitation problem, the plugs almost looked brand new, dont bother doing this, if you dont have to. The mag side is a real pain and you need different tools to change it. the normal tool that comes with the tool kit will not do it.
