I had a couple of broken bolts on my intake manifolds and removed the engine shields to gain easier access. Do these shields act as a passive cooling system for the engine or can I run the car with them off. These are the shields that go over the cylinders and along the sides and back.
Definitley needed for cooling. They control the air flow.
