P550943 Donaldson Filter

Well-It's a filter, it filters. I don't tear them apart and run scientific tests. I use this filter for my S&S Diesel Motorsport Gen2.1 CP4.2 Bypass Kit. It fits. It filters.

This filter came highly recommended as a quality product and fits perfectly. It also comes wrapped in plastic keeping debris out of it!😃

Fits the SS Disaster Prevention Kit on my 2013 Ford F250 6.7 Powerstroke.

The filter I got was a real donldson filter. I would trust this company.

Bought this to replace the filter on my aftermarket disaster prevention kit on my 2014 Ford 350 super duty 6.7l diesel truck. It’s the exact replacement and seems to be working perfectly. Simple to install, just relieve the pressure by unscrewing the valve on the bottom filter housing and unscrew the Donaldson Filter and remove it, and screw this new one back on. Don’t forget to cycle the key and let the fuel pump pressurize the lines at least 10 times or more. Just listen to the pump and you can tell when it’s primed otherwise your truck will not start. I changed this filter while I was changing my other two fuel filters, and I’m going to just keep it on the same rotation as them

Works great on my disaster prevention kit.

I change this filter every other oik change. Work as should

Good value for money. Used on my 2012 f250 s&s disaster prevention
