Blitz LM filters are all cotton gauze, weather it be panel filter or induction kit
SUS are stainless steel mesh
Sonic filters are cotton gauze, being phased out and replaced with Advanced power, same as sonic, but stainless mesh filter.
Blitz only make the LM panel filter for the 350Z, they say they had problems with the check light coming on when they tried to do an induction kit for this model.
Hope this helps.
