Using the APR Carbon Fiber Vortex Generator is easy. First, clean the area on your Subaru WRX or STI where you'll install it. Then, carefully attach the generator according to the provided instructions. When it comes to driving, you'll notice better airflow management right away. Remember, this is a clearance item with top - coat damage and chipping, so it's non - returnable. For maintenance, regularly check the attachment points to make sure they're secure. Clean the generator with a mild car cleaner to keep it looking good. Avoid using abrasive materials that could cause more damage to the already chipped top coat.
