Although it didn't appear to make much of a difference on the Dyno (Dyno results posted here - ), for what it's worth, here's what we did:

First, you have to remove the front 'decorative' cover section connecting the two intakes (already removed in these pictures). It just pops off, there's a clip under the front lip of the cover.

Once the cover is removed, there are 5 titanium screws to be removed for each side (make sure you get that last one in the back, or c-c-c-rack). You need a star or 'Torx' screwdriver to get these screws out. Also, you'll want to loosen the bands that connect the hoses to the filter casings.

Once you have them loose, you will find the secondary charcoal filters up underneath the covers.

We just pried the filters out with a screwdriver, leaving the plastic frame for the filter behind (also allows for a quick reinstall, should it be needed). That was it!
