I believe, however, that the Cat filter does not have a water extractor. Not necessarily a big deal, just want you to be informed.Yes the CAT filter is just a wee bit larger in diamater and a little bit longer. I can be bought at any Truck servicing center or CAT service center for about $10. The adapter required to make it work was developed by Greg Landuyt of www.lubespecialist.com fame.
I have one on my car and it holds up really well and you can go more miles than the stock if you are getting good quality fuel.
