plenum torque specs

[chevyhome]

Does anyone know the torque specs on the upper to lower intake plenum for a 93 lumina with the 3.1 engine?

i never bothered to torque them down. just make them reasonably tight.

pretty much. I think the official number is like 12 ft/lbs or something low like that. But I always just tighten them down.
