Sand and finish your existing part to use as your new mold. This female mold will provide you with smooth finish look in the engine bay.

Yea, and considering you recommended that to me I am kicking myself now.

You are correct but I do not want to make another one and am happy with the current one. I will be spraying the inside and outside of the box when all final prep is finished.

I am not sure how many points of contact I should have for mounting but I am thinking 4 maybe only 3 should suffice. Problem is finding proper mounting points and not having to punch new holes in the sheet metal.

So I finished the final fitting of the airbox and snapped some pictures. I had to get rather inventive with mounting the box. I used only existing mounting points and holes that were already in the engine bay.











And lastly here it is painted and with all the hardware mounted and ready to be put in tomorrow morning.

Nice piece of fabricating work there. Looks good!
If it don\'t work, mess with it. If it breaks, it needed replacing anyway.

Ok so I got the whole thing mounted up but have put on the top insulating tube yet. This generic filter will be replaced with new smaller cyilndrical filter later. Here are the pics.











Here is the clearance from the hood which will only be better once I get the new filter.

Nice. Any plans for a seal/finishing trim on the top edge?

Yes sir I put that on this evening and have some pictures. Here is the final product and the way it will sit.







If there are any suggestions or comments on something that may make this better let me know.

Nope looks good to me. I used very similar stuff but smaller diameter as you would have seen. It must work as the inlet temp sits steady at, on average 3 degrees above ambient while stationary.

Good job!

I wish I had some way of measuring the temp inside the airbox. oh well. I am very happy with the way it turned out and the car feels like it is a little more responsive but this could just be my wishful thinking.

Do you know where I can find a silicone intake tube to replace the ugly one attached to the intake manifold?
