Sinking Air Filter

[Whiz]

Greetings all.  When I first got Ole Red, I checked the Air filter and noticed it was sagging down into the filter box.  I assumed (always a mistake for me), that PO must have gotten a filter that was a little too small.  So I got a stock size replacement (CA3901) and put it in. Seemed to line up ok. I checked the air filter today to see how it was looking and it was sunk. Basically it is long enough but the sides could be a bit wider for support to keep it from sinking.  So, now I wonder do I have a non stock filter box?  I tried to kinda search around for a wider filter of the same length and found this one  Spectre Performance HPR3901 for 20 bucks.   :(

That's a stock box, the one clip on the engine side is not. It's probably just stretched some from heat and age. You could try cinching it together a little with something through the box below where the lower part of the filter would sit. Not sure if it's really necessary.

I've noticed that the air box can get a little warped. Make sure it's properly closed and all the clips are in place. It should kinda clamp down on the foamy bit around the outside of the filter to make a seal.

Ok thanks, Yeah I was considering it just being Warped as well.  The one different clip I picked up at a Yard as it was missing.  But clamps pretty firm.

My air filter does this on both of my MJ's, I'm considering just converting it to a cone filter to get rid of the box and fix the problem.
