The other day I was caught in the rain and had no wipers (PO had removed them). No problem, I had them in a box and 2 minutes later they were installed. That's when I tried the washers and found the fluid leaking out from under the car. Uh oh... there were no lines running to the nozzles. Luckily I got the exact lines I needed on ebay and figured out how to connect everything together. Just waiting on the hose clips to arrive, currently have gaffers tape holding the lines in place.
While I was under the front cowl, I decided to do some cleaning under there. Then I saw the air blower and remembered
SOS selling a HEPA air filter unit. Yup I checked and it was $650 and very pimp in the CF version at $800.
I'm not rolling in that kind of dough so I did a homemade version. I'm sure it's nowhere near as good as the DF one but it's easy enough to remove without any damage.
Step 1: Undo the rubber molding along the front of the cowl
Step 2: Measure the opening to the cabin air inlet (4 x 6")
Step 3: Take a home furnace filter, I had this one:
Step 3: Cut it down to size and remove the cardboard. Flatten out the pleats. I added 2" in each dimension for wrapping it.
Step 4: Wrap it on the duct, wire side down. Fold the edges around the corners neatly. I had some silicone tape which adheres to itself so I used that. But gaffers tape or duct tape would be fine too.
Step 5: Button it up and enjoy the cleaner air! If you drive in the rain make sure to check on it often to see that's it's still in good shape, these filters were not meant to get wet. Although there aren't any holes anove that area, water could still get in some the sides of the cowl.
One day when I make the big bucks I'll buy the DF one. The huge filter size, pleats and depth makes it far superior to my simple hack. But hey, it's better than no filter at all!

Oh, also got my NSX-R lower chassis brace from SOS. I think my car is too low cause it's hitting the swaybar. So I had to order their spacer kit too.
Not gonna go with the front bar, don't want to cut into the radiator shroud. (and the install looks like a major PITA)
