Anyone know where to find a air intake boot from connection at valve cover to turbo? Mine is cracked badly and the dealer wants $75 for a piece of rubber. Or have pics of mods that will work?
Early '99 7.3
I'm currently running stock intake w/ K&N
Thanks for the help, I couldn't find much searching old posts.

GET RID OF THAT THING IMMEDIATELY!!! Replace it with a regular paper element filter. Or buy the 6637 kit and go that route.
There is nothing wrong with the K&N filter as long as it's used properly. This includes proper cleaning, oiling and fitment in the box. Just make sure your box is sealing and you will be fine. I have seen several trucks with dirty intakes and in all cases the issue was a cracked or warped airbox lid, missing clamps, improper installation etc. I've seen it with factory Motorcraft filters as well as FRAM and other brands that people commonly use so it's not limited to just the K&N brand.
It's best to disconnect the intake tube from the airbox lid when replacing/servicing the filter. This allows you to positively engage the tabs on the lid into their hinge hooks and then clamp the cover down on the other end. Re-attach the intake tube last. With this procedure, the box should seal and there shouldn't be any problems. (assuming the box isn't cracked or warped etc).
I've been using the same K&N drop in filter for well over 200k miles. Here's what my airbox and turbo look like. You can still see the inspector's stamp on one of the turbo blades...

Id bet the failure point for the K&N has to do with the reoiling. Which would make it user error and not K&N's fault. But I personally would rather use a paper filter and change it every 6 months than worry about if I used too much or too little oil.
I had K&N before and it served me fine on that truck, but 6637 is the filter of my choice for this truck.

To each his own.
Too little oil would be bad. Too much won't hurt a thing. No such thing as too much oil on these engines (no MAF sensor...).
Most times it's an issue with the box from what I have seen around here. Quite a few factory airboxes that are cracked or warped or have some other issue. I think I'd like to get an AIS one of these days but then I'd have to get two....

You are correct....to each his own.
I dont see how too much oil could hurt one of these truck.. since from the factory they practically inject oil into the intake tube anyway

Agreed. There was a thread a while back (maybe on the Heavy Duty forum) about being careful not to over oil the reusable filters. The issue is on the gas engines that use a MAF sensor, excess oil would collect on the wire and skew the readings or damage the sensor.
I think my housing lid is not fitting properly- good point. I have not had any over oiling problems as none of my trucks have MAF- and I am always very peticular about my oiling. The other filters that look good are the S&B which Riff Raff Diesel sells- their cold intake kit is tempting. I need to get my craked boot problem fixed first though.
