Travis, I don't think I would go 22lbs on the plugs. Thats about the torque on the cly.head nuts themselves. I don't recall the torque settings in the factory manual, but I think 22 lbs is on the heavy side. I'm not trying to be a smart ass here, but I can't remember when I last used a torque wrench on spark plugs much less talking about plug torques,even in VW schools. I could be wrong. I would use my own judgement here. Bently manuals are very good,but I have found a few errors compared to the original factory manuals.
Maybe someone can help us out here. I might be "leading us down the garden path" but I can be corrected if need be.
