Heat Sheild Question

My 2.7 manifold heat shield is almost history. What would it effect to just ditch shield. This is a real question!
Thanks

 

If your current heat shield is loose, it would make your truck quieter.

 

Yeah, that's the problem. Old as dirt! Cracks in every direction. Also around all but 1 bolt.haha Just wondering what is it sheilding the heat from.

 

On a high performance engine it can help to shield the intake manifold from the heat from the exhaust manifold (non-issue on a 2.7 since they're on opposite sides) and it can help protect any wiring that's close to the exhaust manifold (I don't think there's any on a 2.7?)

If you want to rip it off but you're worried about excessive heat, you can always just wrap it with manifold tape, but I really don't think it'd be an issue. Seems like most of the time the heat shields are only there to keep the mechanics (or sue-happy owners) from getting burnt when they're working on a vehicle.

 

Cool, I was thinking maybe the ac lines needed to be shielded.
It will be getting rid of bothersome noise! Thanks
