I picked up this idea from a DA owner, Speed Daddy. This project to me seemed like a cool idea I am using this stock airbox to hide my K&N airfilter (which resides outside the engine bay and underneath my bumper. and is attached to tubing that is expandable (kinda resembles the old clothes dryer tubing). In essence its a DIY Cold Air Intake. I never have to worry about the cops saying, “this is illegal, I’m writing this up”.
So what I did was found a donor 92-93 air box. Thanks to David Yue for the airbox sale. I put a strip of metal strapping that slid into the horizontal opening of the bottom half of the airbox. For this part of the project you can use any year integra. I screwed the 2 ends together. I put some Blue tape over the opening of the horiz. opening so that when I apply the sealant it stays put. I then took my Good Stuff foam sealant sprayed a generous amount of foam into the cavity. The strapping material is important to the project as it is being used to hold the foam in place, other wise in time, the foam will be sucked into the intake chamber.
Next I took the lexan, a paper plate, pen and lexan cutting tool, as well as a level to scribe my straight line.
The paper plate is used so that I can make my template for the top half of the airbox. I then just transfered the template over to the lexan and began cutting. Once I got my desired shape I then pealed of the protective covering from both sides of the lexan and shaped it until it fit into the slot of the airbox. I bought some black silicon sealant and put a nice bead around the entire area where the lexan will be sitting on. Your job is now half way there. I had to wait over night for the foam to cure. It will expand as you see in the picture. You will need to get a long razor to make a smooth cut away of the excess foam material. Once I was happy with the cleaning, I took some black paint and applied a good coating on both ends including the screws and strapping material. Allowed it to dry a few minutes then put it back in. by now the lexan should be sealed enough onto the airbox that you can put it into place on the bottom portion. take a clean cloth and wipe your finger prints away and enjoy your easy project. Remember to take the excess black sealant off before you let it cure over night.
Here’s some pics to show you the progression.
Let me know what you think.

The taped off area of the cavity that I sprayed. Wait at least 12 hours to allow the foam to cure and harden. Follow the instructions carefully on the can or you’ll end up with a big mess (from experience). This stuff is very sticky and a PITA to get off of your fingers. Once the foam has time to cure, remove the blue tape and trim if necessary.

This is just an example of where I put the strapping. Mine went all the way across. If you have a Dremel, I’d recommend removing that mounting tab or foot. It makes replacing the bottom half of the air-box, easier (this one is the donor portion) onto the car.

The final product, now mounted back in place.
