It seems as if I'm the only one who uses an OEM filter (rather than a K&N) with the z-tube. Are there any other people out there doing this?

 

nope! why not just replace your stock filter with a better performing one? if you don't like k&n, try the amsoil filter. nano fiber and it doesn't use oil.

 

i'm currently using the OEM filter until it gets a little dirtier, then I plan on replacing it with the amsoil nanofilter

 

Nanofilter is a good way to go.. even Fram came out with a nanofilter.
not sure I would use that one though.
AEM makes a polyfiber filter in a cone only (fits Stillen CAI, etc.).
None of these need oiling. Just washing or blowing out with low shop air.

 

yes. i have z tube with stock filter. i have the amsoil nanofilter sitting around until my 30k comes up.

 

I haven't been able to find the conclusive part number... do you know it?... I've been considering that filter but last I read no one really knew the correct size/part number...

 

a few do... there have been some real world tests... Nissan Sport Mag did a brief write up, and I think more testing is being conducted... Most that go with Z-Tube use a cone filter though...

 

the amsoil part number is eaA74

 

i was till yesterday lol

K&N ftw!

 

is that the panel filter or cone filter?... I have Stillen CAI so I need the fitment to replace the K&N cone filter and accommodate the ventury/velocity ring...

 

if you know the part number for the filter you currently have, you can input it here to cross reference it with the amsoil one

 

it's the panel. sorry, don't know about the cone.

 

I figured that there was not a noticeable performance gain to justify buying a $40 filter. $8 every 15K isn't such a bad deal, considering that a brand new filter will be 100% clean.
