The old housing was in bad shape - the plastic lip was clean melted off and the gasket that fit within the black lip was in bad shape split down the middle throughout the length of gasket.

Yeah, 15-20 should be ok. Those metal inserts in the plastic will prevent any damage as long as it's not super over torqued.

Spark Plugs are 17 lbs in my other car.
