I am wanting to replace the non servicable air box in my 06 zx4 se i atempeted to make my own. I was able to make it work but I was pulling way to much air and it was causing me to pop codes left and right and running really delayed. Any ideas or any aftermarket kits possible as I have found none so far.
Thank you

Welcome to FF!

There are a couple ways to do it that work, and there are threads/stickies here with info./pictures to help.

Basically two options (cheap style) that are generally called the "stealth CAI".

One involves putting a cone style K&N or equivalent at the end of the MAF tube in it's current location, that gives you a "cold air" system as it's low behind the front splash guard.

The other involves using that MAF tube turned backwards & attached to the rubber connector for the throttle body. Needs more modification, don't forget to turn the MAF to face the right way or you'll get codes.

It's gonna pull the same amount of air regardless of filter, your MAF's ability to accurately measure the flow is a different issue.
