Using this COBB Top Mount Intercooler for your 2022 - 2025 Subaru WRX is straightforward. It's a direct replacement for the OEM intercooler, so you can simply swap it out. You don't have to make any tuning changes, just install it and it can run on the stock Subaru calibration or COBB Stage 1 OTS maps. When it comes to maintenance, keep an eye on the black powder - coat finish. If you notice any signs of chipping or rust, you can touch it up to prevent further damage. Check the connections regularly to make sure they're tight and there are no air leaks. Also, clean the intercooler periodically to remove any dirt or debris that might reduce its efficiency. As for precautions, always disconnect the battery before installation to avoid any electrical issues. And when handling the intercooler, be gentle to prevent any damage to the core or end tanks.
