I'd be afraid it would fall out of the seal with no outer support since the LBZ filte fits inside the tube and the intake kit filter most likely fits the seals on the outside of the tube.
I guess the AFE or the K&N wouldnt be too bad. Only time I'd need any extra flow the headlight would be...
I did look a little for an S&B seeings how they filter so well supposedly. Guess I didn't look in the right place; all I found was complete intakes.
That AFE seemed like it blocked a lot of the intake tract w/ the endcap. Almost like you'd have to run it w/o the lid for any gains.
