Cold Air Intake heat shield

Hey guys I like to make things so here is my cold air intake heat shield that i made. There wasn't any really good heat shield to my opinion so i decided to make my own. It took me long time designing this heat shield because i want to be able to fit big filter. This heat shield holds a lot of cold air, good for high rpm under full load. The bigger the filter you can fit the easier your engine breezes.
Here are some pictures.







I haven't tape the foam yet because i'm going to use a better one since i had that one laying around i used it.




Tight fit here is the in print of the hood.

Nice seal all the way too shock.

not bad....what's the material, abs plastic? pretty much looks like most of the other ram air heat shields, going all the way back to ECIS. Nicely done for a homemade piece though; except you don't have any mount points and yes, as you've already stated, the foam looks a bit cheap.

One problem.

Remember this is a HEAT shield, so you want to stop HEAT.

Yet where the Coolant Expansion Tank sits you've left this gaping hole.

Plug that, and I'll be half impressed

It's amazing to me that a non M E46 is such a beautiful car but the E46 M has never done much for me.

Nice job, but i think you should consider blocking the expansion tank as it gets really hot.

i have 3 mounts that heat shield isn't going anywhere. 2 on the bottom and one hidden under the foam.

not exactly, my heat shield has a lot more room for air and k&n heat shield has a gap near shock, don't think that gonna make any difference but its there, and bolts to hold the shield together, looks a bit cheep for paying that much.

No offense, but 3 years?

Fresh filter and drycharger (filter sock) once a year for me. Gotta pay to play.
