Using your DC Sports air filter is easy. First, find the old air filter in your intake system and remove it. Then, attach the new DC Sports air filter to the intake tubing using the included clamp. Make sure it's securely fastened. When it comes to maintenance, check the filter regularly for dirt and debris. If it looks dirty, you can clean it with a filter cleaner solution and let it dry completely before reinstalling. Keep in mind that you should always handle the filter gently to avoid damaging the cotton gauze element. Also, make sure to store the filter in a dry place when not in use.
