First off, I'm not anyway affiliated with Filtration Solutions, just bought the product. Anyway, the bypass filter kit for my 2006 PSD consists of a new engine oil filter cap, new oil pan drain plug, the filter housing and manifold, oil lines (I opted for the stainless braided ones), various fittings and some really good instructions.
Here's how it works; on the 6.0L PSD the oil is extracted off the top of the engine oil filter through a small threaded opening. With a 90 degree AN fitting it runs via the hose down and below the cab to a spot where I mounted the filter housing. I put mine on the driver's side just behind the transfer case skid plate. After it is filtered, it is returned to the engine by the new oil drain plug, also with AN fittings. The filter housing has a port where you can draw an oil sample with little to no mess. It took me about an hour and a half to do the install. I only drilled one hole in the frame and used an existing hole. Neat and out of the way.
Talking with the guy before buying, it was clear they did their homework by researching SAE documents and designing a filter that worked in the range of particles that damaged bearings and bearing surfaces; from about 10 microns down to 3 microns. Anything large will be filtered by the engine filter and anything smaller will simply flow through the bearings in the oil film and cause no problems. I've got about 500 miles since installing the filter, changing my engine filter and putting in fresh dinosaur oil. When I pull the dipstick, the oil looks just like I poured it out of the jug.
If you read the testimonials on their website, some of the OTR diesel guys have run their rigs 30,000 miles before a change; but they also do oil analysis to make sure. When I rack up 7500 miles, I'm going to do a full change to synthetic and start the oil analysis myself. I'll keep making updates when the analysis is done so everyone has the data.
The kits for the 7.3L PSDs actually plumb to existing ports on the engine and are a little simpler than the 6.0L. I think they are working on Cummins(Dodge) and Duramax as well. All in all, from my early view, a great kit and way to keep them running far beyond the normal life.
The filter only filters a small portion of the oil, not starving the upper end or the lower end. Through this process of filtering a small portion, all the oil gets filtered with no potential problems and no junk ends up in the oil pan. Take a look at their website for the editorials and the pictures of a Cummins they pulled down. It is amazing!

If the webmaster will let me, I'll keep this posting going and attach pdf copies of the oil analysis as time goes by.
