Rust inside K&N Tube?!

[Abn Panzer]

Taking various things off the engine today, to paint, and noticed that when I pulled my CAI out that there was rusting on the inside of the metal intake tube on my K&N CAI.

When I rubbed a paper towel inside the tube, to see how rough it was/check for flaking, I didnt see any flaking but noticed the towel/rag has powdered rust on it.

What is this doing, if anything to my engine? Can I/Should I do anything to it (other then get a different CAI) to prevent it from getting worse or make it better? The outside of the tube/intake has NO rusting on it at all which made me suprised to see the inside did.

Only thing I can think of is when I 'cleaned/recharged" the filter I might have put too much oil on it and it got inside the tube.

Any thoughts?

i would call K&N and tell them and see if you can get a warranty replacement!

Yea, that is NOT GOOD to get into the TB.

i dont think that putting to much oil in the filter would cause that. oil wont rust thing, keeps things from rusting. my two cents

Good call!

Just sent them an email and got a reply within the Hour that they needed a mailing address to ship my replacement too.

Got to like that!... of course would have liked it better if it never happened.
