Which risk increases significantly when an engine overheats?

💡 Explanation

Reduced material tensile strength is the risk involved, because thermal expansion and increased atomic vibration lead to yielding through thermal weakening rather than improved airflow; therefore engine components warp, rather than improving performance.
