Ans: Adding an aftermarket air intake, such as a cold air intake or a high-flow air filter, can affect your vehicle's maintenance needs. One of the primary maintenance considerations with air intake is the air filter. The type of air filter used can influence maintenance needs. Some air filters, like oiled cotton filters, require periodic cleaning and re-oiling to maintain optimal performance. While a CAI can improve airflow and potentially increase engine performance, it may also require higher maintenance based on the model you are choosing.
