Feel free to add your favorite brand of automotive oil filter to the thread.
Here are some pictures of a Fram PH8A and a Napa Gold (made by Wix) 1515 oil filter, this is a popular filter for Ford. In the pictures the Fram is on the left and the Napa Gold is on the right.
Here is a picture of the base of the oil filters, anti-drainback valve, and the bypass valve(listed in order from bottom to top). The Fram anitdrainback valve that is attached to the by-pass valve and is very thin. The Napa Gold has a very thick silicone anti-drainback valve. The Fram has a nitrile rubber anti-drainback valve.
The next picture shows the filter media. The Napa Gold has way more filter media than the Fram. The Fram media feels cheap.
The Fram relies on the spring to seal the top of the filter. The end cap are made of a fiber board. The Napa Gold is sealed off and has a steel end cap.
Last the springs in the end of the filter. The fram uses a clip spring that can bend under pressure. The Napa gold uses a steel coiled spring. It seals the filter element to the base plate and prevents dirty oil from not getting filtered. The spring also holds everything in place inside the filter.
