Injen CAI filter replacement...

[mazdaspeedster3]

Does anyone know the part number for the air filter on the Injen CAI? Looking to purchase an additional one that can be installed while cleaning the original... Any help would be appreciated. Dont have time to hunt.

I couldn't find the part number exactly, but I figured this could help. Atleast this way you could measure your existing filter and match it up with this list:

Injen's website is pretty worthless and doesn't work half the time.

Also if anyone knows how often to clean / replace the CAI.
