Hey, I'm new here but have always loved cars. This project will be for an Audi S4. For our car platform however, the intake options are less than ideal - otherwise I would buy one. 

An expensive but poor design:


This intake design is ideal, but it isn't for our car and serves as the inspiration for the project:


That said, my idea is to construct a snorkel that could work in conjunction with one of the heat shield only designs as such below:



Now, while I have never done any projects like this - I am pretty handy and learn quickly. I am looking to make a permanent mould, so that it can be replicated... but I have to design the shape first. I'm sure more questions will arise, but the two that I can think of are:
1. What is the best method to create an accurate mould?
2. If I make it a two piece that surrounds the filter, how do I set the threads for the screws to bolt down the lid? (See below for example):



Thank you SO MUCH in advance!!!

Yes, a sandwich core will reduce intake temp, because it insulates the inside from the hotter engine bay. But I really don't think this will made a significant performance upgrade, unless you are really going race specs here.
This will absolutely be a (at least) two piece mould.
Knowing that I will be the fun killer again, I would advice you to put back your idea and start with something far more simple. Even if you are quite a prodigy, you will have trouble with this as a first project. This not only comes down to simple questions like if it needs to be two piece mould, that you can just clarify at a forum, but to get some feel for techniques, materials and processes.
Trust me, most of us paid the early ambition price. You will get a steeper learning curve by starting with a one piece mould project, at sorting out problems one at a time (few at a time, to be honest), at save money.

Thanks for your reply! And I would much rather have real advice - even if it puts a damper on ambition. I am just trying to solve a problem with this relatively hot engine bay, that progressively produces more heat with some specific modifications. Many who have had the car longer see this problem and look for any way to help. Provided I make an investment to create this with that goal in mind, I might be able to make them for others.

And I totally get your point about the learning curve. That is why I was considering making the intake tube first before doing the airbox. That way it is much more simple (although not a one piece), but would allow me to experience a more simple project first. The only difference is that I would most likely be replicating the intake tube I purchase instead of creating a mould for it. Thoughts on this?
