2. Potential for heat soak: Top-mount intercoolers can be prone to heat soak, which is the buildup of heat in the intercooler core, leading to a decrease in performance.
3. Visibility: The position of the top-mount intercooler can make it more visible than other types of intercoolers, which may not be desirable for some drivers who prefer a more subtle look.
Conclusion:The Cobb B42405-BK Top Mount Intercooler for 15-21 WRX is a great option for those looking to improve their engine's performance and throttle response. Its high-quality construction and ease of installation make it an attractive choice for DIY enthusiasts.

In great shape and no damage. The only thing I cant find is the large bolt that connects silver bracket to charge pipe side of intercooler. It is used with about 10,000 miles of use. It comes with charge pipe, rubber couplets, and all other hardware in photos.
