      The Ultimate Oil Filtration for your Powerstroke is here!  After over a year of field testing, lab testing, and design, we are proud to bring the CAT oil adapter to market for the 6.7L Powerstroke!


      Which filter is best for me?

      The same adapter can run either the 1R-1807 or 324-2598 filter.  The advantage to the 1R-1807 is the extra oil capacity it holds.  The advantage to the 324-2598 is the shorter length for those who see trail/off-road applications or lowered applications. Both filters have the same micron rating and perform the same in flow given the amount of oil the 6.7 oil pump can flow.  The Powerstroke oil pump will never be able to push enough oil to overwhelm either filter.  We found the oil breaks down well before either CAT filter decrease performance based off contaminates.  Simply put, the CAT oil filter can take anything the 6.7L Powerstroke can throw at it!


      Leak Testing

      In addition to real world testing, we performed 3rd party lab tests.  The first test was a hydrostatic burst test at 200+PSI at an extreme low temperate. At the worst conditions possible, with oil being viscus and rubber seals wanting to shirk, we wanted to know the adapter and filter would stay sealed. The CAT filter and adapter were able to hold a higher pressure than an OEM Ford oil filter before starting to leak.  


      Flow Testing

      Our second test was a flow restriction test to compare the flow of the CAT filter vs OEM. With a lower micron rating, comes the question of how well does it still flow oil?  Both filters in this kit are rated as Advanced High Efficiency.  This is where the massive amount of filter media inside the CAT filters gets to shine. The increase in flow from the CAT filter is shown immediately and the efficiency increases as the flow increase.  At a flow of 30 LPM and on, we saw almost 2X the flow from the CAT Filter vs OEM.


      Why This Filter is a Safe Effective Upgrade

      The CAT filters we chose for this kit are designed for the harshest environments to filter large amounts of oil at a high flow between long service intervals.  With the 6.7’s oil capacity and oil flow, the filter is only entering its life by the time the oil is broken down and ready to be changed.  It would take a major engine failure to ever try and clog this filter.  The 6.7 Powerstroke has a relief/regulating valve built into the oil pump housing. This is commonly missed since it is not visible unless the front cover is removed from the engine.  Simply put, the 6.7 Powerstroke oil pump is not able to overwhelm the CAT filters we offer in our kit.

      The 1R-1807 is a big difference from normal motorcraft. Took my engine temp down a few degree’s. Very easy to install and the looks of it are great as well.

      I saw this on Tik Tok. I've been following Mark and his crew. This is a great product. It went on easy looks good. The Ford dealership in stalled it when I went in for an Oil Change on my 2017 F450. They were like this is bad ass filter kit. I was like I know!!! I have the CAT 1R-1807 system. It does not hang low. I have a large oil combined with with kit I know use 17 Quarts of oil and have plenty of oil in the truck. Love the kit. Great job guys!!!!
