I saw this when I first got my cayenne. I would stick with the stock intakes. The cosmo intakes suck hot air from around the motor. While the stockers may not flow as good as the cosmo's they still pull in cold air.
They are only effective, if you can fabricate the heat shields for them. I have them and they work quite well. I used two 3-gallon capacity square plastic trash cans cut in half. I took the OEM heat guards and screwed them into the bins, so they don't melt...being so close to the exhaust. To prevent the heat shields from moving - you have to replicate the twin pegs that secured the factory air boxes, to the engine bay.
The sound is INCREDIBLE. The P!G breathes so much better, with cone filters.
I'm considering this one as an option along with their bypass pipes. Seems to be little info available, though. For 30%+ discount over competing brands, it may be worth it. Does anyone have experience with them?
Old thread but I wanted to add my opinion, as I researched around of whats avaliable on the market and also building my own etc.
The Cosmo intake system is $264.50 as of 5/28/16
This intake system replaces the MAF sensor tube and the bumpy flexible pipe portion too. Compared to other intake system I have seen, this has no 90 degree angle. Only one 45 degree turn and one I'm not sure maybe 20-30 degrees towards the filter.
The sharper and more turns air has to get through, the more turbulence and lost of velocity.
Pro: Less turns and degrees, lower price, changes two additional pieces to smooth piping.
Con: you'll need to make your own heat shield. Unknown Filter
Not sure if this is a con but they claim 7HP, which is believable.
Hanksville Hot Rod HHR & FABSPEED/Evoms
As of 5/28/16
$435 HHR
$595 Fabspeed/Evoms
Both does not replace the MAF sensor tube or the bumpy flexible pipe portion.
The Fabspeed/Evoms has an advantage over the HHR as you see they tried to improve the 90 degree turns where it exits into a wider turn which will reduce the turbulence.
The HHR is easily replicated minus the heat shield.
Check out NON-oiled high flow filters. Stay away from K&N unless you feel like buying new MAF sensors. I would recommend BMC filters.
Why do you suggest avoiding KN filter?
I've always used them in all cars and had no issues with MAFs. As long as one knows what they're doing when cleaning and re-oiling it shouldn't be a factor.
I would say any CAI other than stock is gonna be snake oil. As hot as these motor compartment gets even the stock boxes struggle to flow cool air.
The only way to get a true cold air on these would be sourcing directly ahead of the intake at the grill. Don't waste your money for something that just looks cool.
You're paying a lot of $$$$ for throatier sound... which is really nothing but a loud snort of air. I just sold my Ram Filter CAI(paid $200/sold for $150), because I got tired of always uninstalling it just to pass smog. My improvised, cold air isolaters were two cut-up trash bins, attaching the original metal shield to them. In the end, pleated paper filters are still the best... as long as they remain clean.

For a NA car I'd agree they are close to snake oil. On a turbo car probably not so much but there is likely more to be gained by opening up the pressure side. I've not gotten around to doing either though.
Total $187 shipped (ebay prices) or aluminum $162"
When I finally built mine I changed the 90 degree silicone to 45 degree and a 45 degree aluminum pipe. So in total the whole setup is just 2x 45 degree angle = 90 degrees. The other intake kits are 90 + 90 = 180 degree

Thanks... Does this look right? Of course I still need the filters.
