These are U.S. made and top quality.
Well known in high performance (off road, drag racing, and us racing applications)
These are high pressure friendly, and feature a reuseable media that can be washed. (stainless screen)
This is the larger 6inch style and it can be mounted directly in place of an oil filter in some applications (not a 914) or onto a remote filter plate for other applications. This is the type of filter used on remote front coolers when you don't want the possibility of carnage trashing your cooler in the event of an engine failure.
This is used, but no leaks, no damage and very reuseable

Jegs is a distributor for them
