Anyone have the part number for the filter used in Rod Bower's ram air system?

I've been wondering the same thing. If someone messages the part number to you, please share it.

Thanks.

The filter number should be written in felt marker on the outside of the aluminum. I'll look for mine and get back to you.

I used a K&N RU-4250 that I got on Amazon.

K&N Filter

Im looking for the filter that Rod used for a forward facing induction io-360, not having any luck finding a part number. The rocket pn is not the right size for mine. My filter is 6 1/2 tall, 4 1/2 forward opening, 5 3/8 opening at the throttle body.

If u don’t get the p/n here I’ll advise tomorrow after I go to the hangar - I have the same setup as you.

A Little Clarification

These are K&N's dimensional descriptions:

Mounting Flange Inside Diameter:

Filter Base Diameter:

Filter Top Diameter:
Note here - The filter comes with a closed in top, Rod cuts out the center, inside the pleats to provide a mounting "ring" for his Ram Air Valve.

Filter Length: (does not include mounting flange length)

Flange Length:

With these measurements, and the K&N catalog, you should be able to pick out a replacement.

As promised - it’s K&N RU2520

Option to K&N

I've become less enamored with K&N over the years. Has anyone replaced the K&N filter in their Rod Bower filter system with a traditional filter?
