Using this intake duct is easy. First, make sure your vehicle is the 2022 - 2025 Subaru WRX. Install it just like you would with other intake parts. It's designed to work well with popular aftermarket intakes like ETS. When handling it, be gentle as it's made of carbon fiber. To keep it looking good, clean it regularly with a soft cloth. Avoid using harsh chemicals as they might damage the gloss finish. Also, remember the California Prop 65 warning. Don't breathe in the exhaust, idle the engine only when necessary, service your car in a well - ventilated place, and wash your hands or wear gloves when working on the vehicle. This intake duct comes with a 1 - year warranty against manufacturer defects, so if you notice any issues, reach out to the manufacturer.
