Which risk increases when temperature suddenly decreases in a turbocharger's turbine housing?

💡 Explanation

When temperature rapidly decreases, thermal shock occurs because uneven contraction creates stress exceeding the material's tensile strength, leading to cracking. Therefore, thermal shock induced cracking results, rather than oil thickening, compressor surge, or wastegate malfunction, which have different environmental triggers.
