Drivetrain Air intake and filter question...

Air intake and filter question...
Why would I want to choose a cone, cylinder, or panel filter for my air intake? Is there any scenario where one makes a better choice over another? Also the DOS system looked like a great design but I think they are out of business...are there any similar products on the market?

You’re not going to get much if any performance increase from one. Mostly what it does is make those sweet, sweet turbo sounds easier to hear. But the factory airbox does a good job of providing sufficient airflow. It is also a better cold air intake than most of the aftermarket intakes out there.
From personal experience, when was using a cone filter, it sounded awesome, and seemed to give me just the slightest bit more power at low rpm. But at the same time, my intake air temp was running about ten degrees hotter than with the factory airbox. In the middle of summer, that was enough by itself to make me decide to swap it back to the factory airbox, but then I installed a GFB DV+ diverter and it turns out that those are much quieter than the stock DV. So all of my sweet blow off noise went away and that made it a no-brainer for me.
Its really up to each individual how they choose to modify their car. For me the intake temps were more important than the noise and negligible performance increase, but somebody else may not care about a few degrees as much. As long as you are trying to do something to your car, you’re doing alright as far as I’m concerned.

As stated above, you won't get any performance gains by "upgrading" your intake. The factory CAI air flows great, at most all one would "need" to do is upgrade to that dry AFE panel drop in filter. Most aftermarket systems are actually hot air intakes that suck in engine bay air. Granted these engines being forced induction, the ambient air temps don't really matter BUT, any decrease in air temps is a plus in my book. I didn't like the cost of most aftermarket setups so pieced together my own version of the DOS intake. I initially did run the filter directly into the cowl just like the DOS, but found it to be too loud. I played around with a couple different "quieting" methods and in the end a couple of bends made the intake noises a bit more tolerable but still loud enough to hear the turbo. My original cowl cover ended up looking like swiss cheese but they're fairly cheap at around $40 on eMINIparts. I ordered the K&N Orion off Amazon and the intake tubing and clamps from intakehoses.com .

This was a video I recorded when it ran right into the cowl. If I had to put a number on how much quieter the current setup is, I'd say it's maybe 10-15% quieter than what you hear in this video. 1st stop sign is regular acceleration, 2nd was more aggressive. Shifted early to get more turbo noise in before the wind took over.

Love that sound! I’m really tempted to remove my GFB DV+, but just can’t bring myself to do it. I love the blow off soiling the factory DV makes when it dumps! But the darn thing works so well holding more boost between shifts that I just can’t do it, lol. I think my eventual answer for my conundrum is probably to buy a Forge recirc valve, but I do really like how effective the DV+ is. I have an Alta spring too, I guess I could always go that route too.... it’s definitely cheaper, lol.
