The WIX XP Oil Filter 57899XP is an extended performance filter designed for full-synthetic oils to withstand the harshest driving conditions. Suitable for towing trailers, boats and heavy equipment and for extended periods of idling, or high temperature conditions such as driving in city traffic. Also suitable for harsh driving environments such as mountainous climbs, extreme cold temperatures or extended periods at highway speeds. This particular filter is new in box (NIB) and has never been used, making it a valuable asset for individuals and businesses looking to maintain clean and efficient oil systems in their vehicles. One corner of the box has been dented, but this didn't affect the contents.
