No Bubba, your ignorance is now showing, because they actually don't advertise the kit for "better filtration". They advertise it to help you save money, and if you do currently take your truck to the dealer, to make it easy for you to do yourself and save some money. It's actually in the very first paragraph if you would like to go back and reread it also to be more accurate. Like the other Bubba above, get your facts straight before confusing everyone doing research on a particular subject! This is the biggest problem with these forums. They are great resources and I love and participate in them , but a lot of guys talk out there a**es and don't get the data correct or have real-life experience. They are simply relaying information wrong they have read from somewhere else.
