Using the S&B Filter Wrap is a breeze. Just slip it directly onto your KF - 1041 S&B filter. It's made to fit these specific filters on 1994 - 1997 Ford F - 250/F - 350 trucks with 7.3L Powerstroke engines. When installing, make sure it's properly seated to get the best protection. As for maintenance, check the wrap regularly, especially after off - road trips. If it's full of dirt and debris, you can gently clean it with water and mild soap. Let it dry completely before putting it back on the filter. This way, your filter will stay in top shape and work well for a long time.
