Sorry if this is a repost. I have had a Purolator L14459 and Bosch 3312 sitting around for quite a while and only recently noticed that they seem to be nearly identical. With them being so alike I think the purolator wins due to the far lower price than the bosch goes for. Here's the pictures I took. Comments, thoughts are welcome.
same size
both made in the USA, both have a stamp begining with "F05"
same o-ring
same plate and stampings, different valves?
internals of the bosch
internals of the bosch
though I couldn't get a good photo, the internals of the purolator are exactly the same
