Using this DC Sports header is straightforward. First, make sure your car is the 2003 - 2007 Honda Accord 2.4L. Then, simply bolt the header directly to your OEM equipment as it's designed to fit. When installing, take your time to ensure all bolts are tightened properly. As for maintenance, keep an eye on the welded joints regularly. If you notice any signs of rust or damage, clean the affected area with a mild steel cleaner. Also, after long drives or in harsh weather conditions, it's a good idea to check the bolts' tightness. Avoid using abrasive materials on the polished finish to keep it looking great.
