Using this front lip spoiler is easy. Just attach it to the front of your 2004 - 2005 Subaru STI 'Blob Eye' according to the included instructions. When you're driving, be careful not to hit curbs or other low obstacles as this could damage the spoiler. For maintenance, clean it regularly with a mild car cleaner and a soft cloth. Avoid using abrasive materials that could scratch the unpainted black finish. If you notice any cracks or damages, it's best to contact the manufacturer for advice.
