If you have the version of the oil bath that I have, here are some pix showing what it will look like when gutted and with the K&N E-9216 installed. I trim 1 1/8" off the base of the top to allow more air flow, but you can't see this modification when the top is installed. One of the pictures shows a stock oil bath next to a modified one.

Different than described in the Tech Tip, this version requires that the top be completely gutted. The K&N filter fits in perfect and seals agains the top and bottom.

I received an email this morning that K&N will have the E-9216 filters back in stock on July 10.
