Review on 🔩 Premium Polished Billet Aluminum Oil Filter Cap - Ford 6.0L 6.4L Powerstroke Diesel (2003-2010) by Thasapon Keitt

Only criticism is that there is no hole for the Schrader pressure check valve as advertised but it can be drilled and screwed into the upper parts. A few bits of aluminum were still hanging from the threads as I was driving them in, but 30 seconds later the pocket knife solved the problem. NOTE FOR 6.0 OWNERS: Beware of the tall, high-capacity oil filter caps sold by Napa and Wix! A lot of people (like me) don't realize that they are an integral part of the aftermarket oil filters they come with and cannot be reused. Not to mention that they are of poor quality and often fail. I didn't notice this and reused mine with a short OEM filter that would allow the oil to bypass and not be filtered. This blank size OEM cover solved my problem.
