You could just put the Stellings lid on one of these assemblies when you are looking for a more 'correct' look.

I have yet to fit these up together, though I will be soon!

Xtreem assembly
66-3150 for the 2.75" filter
66-3160 for the 4/5" filter.

Air filter, the K&N site lists the same filter number for both! So one is wrong, E-3530.

I did a little more searching and was able to find E-3650 for a 5" x 9" filter.
