Having installed the Nismo CAI in my 2007 Z, I would now like to replace the filter elements with K&N filters. Does anyone know exactly which filters to order for this dual-intake system?
Thanks in advance

 

Why change the filters? The Nismo ones are designed to be efficient and you paid lots of money for those filters.

 

I would like to change them because they have become filled with dust and dirt and do not appear easy to clean.

 

They're definitely re-usable. Below is a "note" from Courtesyparts.com on the intake in their description. They say they're washable in the product description. I assume that means you can use a hose and clean them on the outside and from the inside cone. Since they're not to be oiled just let them dry well and you should be good to go. I recently installed them on my '07 but they're still clean. I don't recall if the instructions said how to clean them. I can check tonight if you want me to.

NOTE: The high performance air filters included in this intake kit are fully serviceable and re-usable. The air filters are dry performance filters, do not oil! Visually check the air filters at every oil change. Under normal street driving conditions, the air filter service interval can be as long as 40,000 miles.

 

Yes, please check how to clean these filters. I received no such documentation when they were installed.

 

Sorry for the delay. What did you do about this? My instructions don't say anything about cleaning, except that they can be cleaned. The parts department should be able to tell you.
