Looks good. Always glad to see new ideas.
One suggestion.
I used the black gasket off the wiper cowl when I did that to my JL box.
Since I swithched to the Street scene wiper cowl it was just laying around.
I did not use the whole piece though.
You could probaly take the OEM one off , put it on the box and put the remaining back on.
It would definately look more factory and its FREE!!!
Just a suggestion.
NICE JOB.

Here is a pic of the gasket I am talking about

Thumbs up BMWBig6

This is one of the best threads that I have read in a long time. Well done, well documented and prob a very good cheap way to make sure you are getting cold air..

What would work, seeing that you have a computer (Epson box in one photo) it that you could remove the can, wrap the bottom with one piece of paper and the sides with another. Then use that as a template to mark where you made your cuts in the trash can. Scan the image into Adobe and post it here for all to use and enjoy.. Heck, we can even name it after you.. But some may have an issue with having a BMW part on their L... LOL j/k

Great work..

WOW!

Always nice to see true ingenuity. What I like is that although it's homemade, it looks really good. Now I bet lots of "Ls" will have the "Rubbermaid Wastebasket Mod" in their sigs. Ford dealers can void your warranty for the Rubbermaid mod.!

But hey...that gives me an idea. Take the same wastebasket, cut a 6" hole in one of widest sides, then a matching hole in the hood. Next, get some bungee cords and strap the basket over the hood hole, running the bungee cords from one side of the hood, over the basket, then clip to the other edge of the hood: Instant Ram-Air Hood!

On second thought...maybe not. (Kidding!)

Major props for the idea.

It looks better than some of the aluminum ones out there.

Rob02Lighting, I like how yours turned out - very nice craftsmanship. Do you like the metal finish, or are you going to paint yours black too?

dboat - that is an excellent idea! That should be a lot easier than measuring every dimension.

jaymz - I think you're on to something there!

I have already decided to try a few more things for version 2.0:

- substitute black rubber gasket or weather-stripping for the tube foam insulation (a la VINNIE)

- cut a hole in bottom of heat shield, and route some kind of ducting or tubing for more cold air

Anyone want to recommend the best material for the tubing? I have seen vacuum hose, smooth hose, PVC, HVAC ducting, gutter tubing, etc. Would smooth tubing be better than ridged solutions?

Also, should I throw out the foam boot stuck in the fender hole (part of the original JDM kit)?

Thanks for the all the comments and input thus far!

I did the same thing about a year ago. Ended up buying 2 trashcans before I got it the way I wanted. I took rubber vacuum hose and used a razor blade to make a cut longways and used that for the trim. Just be careful not to slip and cut your finger (the voice of experience talking)

Nice job, but I think I'll stick with my JLP kit.

Tundra, I'll let you know if I am interested after I finalize some of the details... I don't think I want to make another one, but who knows how I'll feel next weekend.

note: doing this to a stock airbox caused me problems, so now I run this to just a filter.

I'm just waiting to see the first RED one, the first WHITE one, the first BLUE one, yet I've never seen a SILVER trashcan...

Good job.

captainoblivious, what problems did you encouter with the stock airbox, and what do you mean you only use a filter?

CornerCarver, edit your post before people start asking me to photoshop all the different colors! As far as I know, the Rubbermaid 2956 is available in white, black, gray, and tan... but sorry no Sonic Blue.

FYI, I drove by a local auto-body shop to pick up some free rubber moldings and weather stripping like Vinnie used. I will post more pics of the new gasket later.

...
The way I had the tubing entering the airbox shot it right under the lip on the stock airbox, this redirected the air and when it hit the air coming in through the fender it actually created a small vacuum pulling the air away from the maf and intake. The problem was really only created on WOT throttle runs, escpecially dealing witht he tip-in (sp?). Right now I just have the JDM filter.
