Once the old filter is out and the housing is prepared, installing the new filter is straightforward. Follow these steps for a seamless installation:

  1. Handle with Clean Hands: Ensure your hands are clean when handling the new filter to prevent transferring dirt or oil. When you change car air filters, it’s common to have hands dirty, and this can damage them.
