hello,

does anyone know what the inlet size for the NISMO CAI filter is? i'm guessing it's 3 inch. If it is, will i be able to use different brand cone filters and attach it onto the CAI tube? thanks!

you can use different filters im just not sure on the size...

 

I am actually wondering the same thing as I want to change the filter soon.

*** UPDATE ***

Looks like its the 3" filter. Found this online:

NISMO Cold Air Intake G35 03-07


Fits:

- 2003-2007 G35 Coupe

- 2003-2006 Sedan


Genuine NISMO (Nissan Motorsports International) part.

- Mandrel-bent 3" tubing maintains consistent inside diameter

- Designed to prevent inadvertent water ingestion

- Reusable, washable air filter

- Material: 6061 aluminum, 3" tubing

- Precise, bolt-on installation

 

let me know if you guys find a place that only sells filter and it sounds good. I got a AEM DryFlow filter from ebay and it fit/flows fine. I would have preferred to pay for just a Nismo replacement filter but the AEM was the only I found sold separately.

Not sure but it might sound a little funny paired up with my Nismo CAI tubing... Get this fluttering sound when I let off the gas pedal after hard acceleration.

Also, another question... do I need to replace the bypass foam thing on my nismo piping if it's just a little ripped? does it create the noise I'm experiencing or any performance loss? Once again, AEM seems to have the only replacement available for just that piece.
