When should you replace the filter on the Nismo CAI? And forgive me if I couldn't find a DIY but how do you get to the filter to inspect it? The CAI came with the car so I have no idea in what condition it might be in. Thanks all.

 

a. Remove the front bumper.

or

b. Remove the front wheel and wheel liner.

I assume that the filter is washable.

 

dont replace it it is cleanable

i guess if it gets extra grungy you might have to look for a k&n cone or a aem or something but im pretty sure ive never seen a nismo replacement
