Well after hydrolocking last week during a monsoonal downpour and almost kissing my motor goodbye, and the mounting bracket arm ripping off of my CAI and creating a hole years ago (which I sealed with a rubber sleeve and hose clamps), I decided it was time to kiss my CAI goodbye. I thought of cutting it into a short ram, and then I got an idea of a DIY icebox. Would the cone K&N filter fit inside the OEM airbox? Hrmm...let's find out.

Remove your CAI filter and tube if you have one, or your short ram air filter..you can leave the short ram tube in for now.

If you have your stock airbox, find it, and remove the top cover. There are three phillips head screws holding it down. You can also use an 8mm wrench/socket to get them off. There's the crappy OEM filter...blah.



Yank out the old filter. Looks like there's some decent space in there.



Looks like it will fit so far. I had to press it in just a tad to get it to fit.



Put the top cover back on for a test fit. Yep, it fits!



Take the cover back off, and remove the filter. Bolt the OEM airbox into your engine bay, and put the filter back in.



All you CAI guys, this is when you start cutting. I cut mine just before the bend where it starts to go down, for a test fit of the tube. It was close, but I ended up cutting another inch and a half or 2 inches off in order for it to fit correctly. Short ram guys, I don't know if you'll need to cut. Test it to see if it will fit, if it doesn't, eyeball it and make a cut. Take the cutting slowly, better to need to cut off a little more than to cut too much.

Connect the filter to the tube, and put the filter back into the airbox. Then maneuver the intake tube back to the throttle body sleeve and tighten the clamps. Now you have a DIY icebox, and didn't have to spend an arm and a leg on one from Comptech.


The finished product.






Once I drive it a little bit, I'll let you know how it works out. I may cut the bottom of the airbox out so it can get more air.
