Using your DC Sports air filter is easy. First, remove your old air filter from the intake tubing. Then, take your new DC Sports air filter and align the urethane base flange with the intake tubing. Bolt it directly onto the tubing. Make sure it's securely attached. As for maintenance, check the filter regularly. If it looks dirty or clogged, you can clean it with a suitable filter cleaner. After cleaning, re - oil the filter according to the instructions. When handling the filter, be gentle to avoid damaging the cotton gauze element. Store it in a dry place when not in use to prevent any moisture damage.
