I replaced it today.
I could reach it from above- reaching one hand around the throttle body/intake and the other on the opposite side of it.
Not too bad.
Seems to be a bit better, but I'll know more after a cold start.
Just has a bit of a growl.
I replaced all the sparking plugs/wires.
Not the most fun job- and found I had a bad radiator fan motor.
