Yea I saw that video too, looks like he has some weight reduction as well. Video is attached below:

I'm glad you stipulated what you use your car for the filter is defiantly not a DD use cheers.

Just thought I'd chip in with a point I don't believe anyone's mentioned yet, the Takeda intake uses an undersized air filter.

What I mean by this, is that all air filters regardless of if they are a panel filter, a closed cone, an open cone or a HKS doomshroom have an effective area which can be measured in square inches (yes some Europeans still know what they are :P). And the Takeda intake uses a filter with a smaller area than the stock panel filter. I'm not sure if this was something they had to do in order to make the cone fit into the stock airbox or if it was simply a mistake they made during R&D but the aFe cone filter that comes on their ISF intake has a smaller surface area than the stock panel filter.

Now area isn't the only important factor in filtration, the thickness, material, etc all play into it but as a general rule with all things being equal between two filters reducing the area isn't great. The aFe cone they use has ~88² inches of surface area, compare this to the ~94² inches of the stock panel filter and it's obviously smaller, now obviously the stock panel filter uses different material, but the aFe ISF drop in filter uses the same 5R material/design as the cone and so there's potential for a simple direct comparison there: the Takeda intake is more restrictive than a stock airbox with an aFe panel filter.

I hope the info is of use/interest. And for those wondering the K&N cone RR Racing use has a ~113² inch surface area, it's a beast.
