Question K&N Air Intake Kit and using a different filter?

I'm a noob to Diesels, so please throw me a bone on this one. 2002 7.3 Excursion, 2wd. 148k miles.

I just bout it a couple days ago and it came with a K&N air intake kit (filter, heat shield, and pipe run) installed. From what I have been reading, K&N anything is not the best setup for a 7.3. I'm thinking about going with the Ford AIS kit, but really do not want to shell out the money unless I have to. So, my question is can I keep the K&N kit, but use a different filter on it or should I go ahead and do the whole thing? Recommendations?

Thank you for your help!

Keep the K&N intake pipe, Call Riffraff and get their 6637 filter. You can get one at NAPA or any fleet store. Riffraff is the cheapest by far. Good to get 2 at a time because of the shipping cost. I think they are $28.99 but still cheaper with shipping than anyone else I find

Keep the pipe and heat shield , toss the filter , buy an amsoil filter , they make an exact match for the K&N with the screw and all. Been there done that. I don't recall the part number but do know I've posted it up in the forum a few times so it is searchable. The DIY filter will not work with the heat shield so in the thoughts of keeping it nice looking I would avoid that route.

Try this out on Amsoil's site , should be the right one. Few dollars more than a DIY filter , except yours will be cleanable and still look like it belongs. Kind of a no brainer.

Amsoil filter replacement (for a K&N filter pack). EaAU-4095/ K-N RC-4780

Why will this not die... There is no issue with the K&N filters... NONE. They use exactly the same 5 layer filters that AFE and S&B use... The issue has been and always will be the way a DROP IN K&N filter fits the factory air box.

Do what ever you want with your filter box, but don't do it because some internet legend that will not go away tells you to.

Beware, the 2000 6637 filter guys will be here shortly...

yes, I had the dreaded drop in filter in my truck when I bought it. It didn't fit quite right in the stock air box. It would let unfiltered air through.

The filter you have is fine.

I have to agree 100% with CSIPSD. I had the K&N Cold Air Intake Kit on my 7.3 Ex for over 250,000 miles and my turbo looked perfect with absolutely no dusting what so ever. The only reason I switched to the 6637 is because the K&N was stepped on by accident while it was out getting cleaned. Otherwise, I would still have it on.
I would never keep the drop in but the Cold Air Kit worked perfect.
