Ans: Cold air intakes are generally feasible for extreme weather conditions, but there are important considerations to keep in mind depending on the type of weather you're experiencing. CAIs can offer benefits in both extremely hot and cold weather, but their performance and potential impact on your vehicle may vary. These accessories are designed to draw in cooler and denser air from outside the engine, which can lead to improved combustion and performance. In hot weather, the temperature inside the engine bay can rise significantly, and the intake of hot air can reduce engine efficiency.
