Wanting to replace/install paper air filter that will fit this intake tube diameter

The previous owner installed a Hi Flow/CAI AIRAID air intake among other useless things, but I am wanting to replace the filter on the air intake due to how much it actually sucks at filtering and having to clean and oil it.

I’d prefer to not buy a stock box and would rather just find a good replacement filter to replace the reusable filter. I see people say a lot of good things about AC Delco, does anyone know a direct replacement paper filter?

has anyone here done something similar where you used any other paper cone filters that would a close to the diameter of the tube?

Here is a picture of what is currently installed:

I'm actually not even sure that anyone makes a paper cone filter. I was under the impression that all of them were made of this material (or whatever the K&N cone filters are made of) that requires constant oil and cleaning. Maybe I'm wrong?
 
I have not read much good about cold air type setups. Mostly not worth the cost and the filters are not very good at filtering. I know you do not want to get a stock box but that would be the best route to go. Again as I have read. I think Jerry has done a lot of research into air filters and has a great write up on here.

I always associate anything Amsoil is peddling with snake oil. However, in this case, that may be better than the oil type filter you have, but I can't imagine by much. I do know those oil type filters like K&Ns are a pain in the butt to keep clean, especially when it's a cold air intake sitting right there in the engine bay.

Yeah so far after looking around, I've only found a replacement filter made by Amsoil that is supposedly better than all the K&N/Airaid type filters. probably not as good as stock, but maybe a good compromise.

The link provide leaves me with a question. It states "This example uses a stock 5.0L Mustang that requires 200 CFM at 3000 RPM, whichis near peak HP performance. After installing the largest aftermarket intake system available, the Mustang only requires 300 CFM at 3000 RPM."...... How does adding the "largest aftermarket intake system available" increase the CFM requirment of the engine by 50%? Sombody please splane it to me.
 
Im not really sure, but as we all know here the High Flow intakes dont add anything to our jeeps

im hoping the nanopartical material is better at filtering then the current airaid filter I have.

It could be a cheaper alternative to finding and reinstalling a stock intake for those of us (like me) that bought the vehicle used with the aftermarket system already installed. From the videos and other forums Ive read it definitely does look like it would do a better job than the K&N/Airaid gauze-like air filters n

I guess underlying my question is, I doubt their claims. The peak power (HP) band for a stock 5.0 Mustang is around 4200 rpm's not 3000. As Chris stated, seems like a bit of snake oil selling. But I do understand your needs as going back to the stock box can be costly. I would check your local bone yard even a totaled TJ will most likely leave the box intact.

Edit: sorry that's torque, HP continues to climb well past 4200 rpm.

Also, it is impossible for an engine to require 200 cfm with one filter to now require 300 cfm with another type. A 5.0L engine will require x cfm independent of the filter that is blocking flow. A 5.0L is also very likely to need >400 cfm since our 4.0L will flow ~380 cfm. I think these guys are selling hype more than a quality product.

@lrb6805 - I'm in the same boat - I love the Banks manifold and exhaust setup that my Jeep came with, but the Airaid intake is a POS that doesn't filter anything (It could probably suck a nickel straight through if I held one up to it).

Did you find a solution?
 
I ended up buying the replacement Amsoil Air filter (dry) and as well as their pre-filter. I looked up my airraid’s filter dimensions (base and tip diameter and the height) and chose the direct replacement off of Amsoils website.

The filter is high quality and looks to filter much better than the air raid filter, though I personally dont have any actual data to support. But just based upon my visual inspection the amsoil filter looks to be much better. I think it’ll be a good compromise compared to switching back to the stock airbox.

These are the part numbers I ordered:
1. EAAU4070 (Universal Air Induction Filter)
2. EAPF19 (Absolute Efficiency Pre-Filter)
