Here's some excellent data collection and testing of stock versus cone filters on the bmw turbo gas engines done by the maker of the JBD. It's more thorough than the little bit I've done, but shows similar results.

I'm using the shortest 4" opening AEM filter. The circumference of the MAF is a bit smaller than this and I had to use some gasketing to make up the difference to get a tight seal.
Also had to loosen the lower clamp for the intake tube and rotate it a bit to get the cone filter to fit in the space shown.
I'm not claiming that a cone filter by itself will give more power ... just on my vehicle with its mods it produced a statistically significant increase in measured power.
