Here you go.

George converted his parking lights to LED which bought him a bunch of room in that area. You will likely want to relocate one of the horns to gain more space as well, but that is no big issue. With the brake duct there it isn't feasible IMO to place a filter back behind the fog light area. If you have aftermarket brake ducts (fog light delete) with flexible hose it would make things much easier.

I tried to reproduce this set up earler this year only to notice that it would work only if the front bumper has gone out of shape, which seems to be the case on the car pictured here. When the front bumper is still cleanly aligned with the fender, there is not going to be enough room in there to place a cone filter.
Worded differently, the edge where the bumper meets the fender should be the widest point of the assembly. On the car pictured here, the widest point is about halfway down the bumper, which is what happens when the bumper goes out of shape for whatever reason.

Pretty sure that picture is from Sean's / JET951's car from some years ago. I see what Thom is saying. I wonder if there isn't a filter with a smaller circumference that could help. I also ran something like this on all my 951's (to date) and the only downside was the rare occasion that water 'might' have got in. I think the NZ solution looks a good idea so long as you have an opening like Shawn's vented headlight cover. While I don't have a pic showing the opening in the new car, we have boxed in the air filter similarly.

"Cold Air Box" almost complete. Taking a bit of a different approach. I cannot use a lid like NZ951 because I am using the LR NACA headlight cover. I will be using formed foam on the hood to seal the cold air box. When the hood is closed the foam will complete the seal. I ordered the foam tonight. I will post some pics once complete. Also, this will keep the engine bay clean and simple.

To me that looks like a good setup Shawn. Will it be a modular system once it’s installed? Be good if you can remove it easily and log with and without the finished setup.

I was **** about this as well.
Years ago I did the hood seal thing, but like somebody said it still gets warm by the air filter from the coolant reservoir (I took temp readings while driving)
I even tried insulating the reservoir with cardboard; stupid.
So this is what I finally did.
Upside:
turbo compressor always sees cold ramed air (you can imagine quite a high pressure zone at speed);
fitment of a good sized filter possible (size of filter behind lights not big enough IMO)
Downside:
brake cooling not as good; 968 style brake cooling scoops help alot;
heavy rainy days not good. Light rain is okay (conventional location behind lights will also get a little wet on occasion; it's acceptable)

Wish I could do that, but I have the secondary Kiss oil cooler down there just behind the fins of the bumper. A smaller/flatter cone filter in the fender may remain the best idea, at least for cars using a Euro front bumper without the side repeaters.

Yes bad when it rains but I hardly ever drive in the rain so no big deal for me.
