Drivetrain ETA on DOS CAI
For us noobs What exactly does a CAI do? If I understand it correctly it creates more cold air, keeps engine temps down and nets 5-10 HP?
Is this something any one can install or I have to take it to a shop? I have never done mods to my cars except rims and exhaust and this one will be my first CAI. I have the jcw exhaust already and will get a tune eventually.

That's certainly a good looking piece and would add to the looks of any engine compartment. Maybe its just the engineering part of me but I fail to see how it provides any cooler or even more air flow than the stock with a high flow panel installed. Does the flapper valve come installed and if so I would think it opens due to vacuum being pulled ? I think I'll take the temp sensor attachment of my Fluke and tape it to the bottom of the stock housing and take it for a ride to what temps it see's.

Also, we still draw-in air from the OEM air inlet.

No, I don't see any issues. We made a 3D model of the OEM airbox before we started designing in CAD. We needed to make sure that our CAI housing did not exceed the dimensions of the OEM airbox -- especially in critical areas like where the strut bar comes across the front edge.

The primary advantages of a well designed CAI are:
A) A larger (in our case much larger) filter that flows more freely than the OEM filter
-AND-
B) A cool air intake source is isolated and insulated from hot underhood conditions.
-AND-
C) A filter and hose routing that does not allow very turbulent air to enter the Mass Air Flow (MAF) sensor.
DoS has these 3 design areas in mind when we develop CAI's.
Our filter has 2.6 times the available surface area of any high flow replacement filter for the OEM airbox. Due to the sheer size of this filter alone, there's less restriction as the turbo and engine pull-in much-needed air.

Sorry that I did not have a chance to respond to your post right away. I needed a moment to get over to the computer at the shop.
Based on less restrictive nature of the larger filter size alone, buyers should expect to see +6 to +9HP with the street version and +8 to +12HP with the performance/track version.
We only sell engine performance parts that make power gains and our initial housing aerodynamics and filter volume show that we're headed in the right direction. Final dyno testing will happen by late July and we'll have the graphs and charts that everyone craves so much.
In the meantime, I think that it's great that folks love stirring the pot a bit on NAM. Unfortunately, 'Sarcasm is the ugly cousin of anger.' So, I only ask that those who want to learn more do what they can to keep things chill on this thread.
Best,

Will the preorders come in at a discount? Does paying $200 now for a preorder save money down the road or is it just to get one of the first ones available?
Really like what I'm seeing so far. Glad you finally got the design sorted out. I'd definitely come check it out at MITM if I was going this year, but I kind of lost interest since they're not doing autocross this year.

Yes, the first batch of pre-order R60/R61 CAI's are being sold at a discounted price as a way to thank the R60 and R61 owners that waited. After MITM 2013 is over (on 08/11/13), the price goes up.

The dry filter media air filter for the DoS R60 CAI is custom, but we've created an adapter kit that allows it to work with many of our competitors' open-filter-element air intakes. -- A dry MAF sensor is a happy MAF sensor.

Here is a pic of the valve. It's the same one used on the noise baffle for the R56 CAI.


As mentioned earlier in this thread, the housing will have a dry carbon fiber look. For customers that want a glossy housing, there will be a $60.00 upcharge. (Email me about this option because it will not be listed on the website initially.)

Is this baffle to be included with the price $326.13? Or need to pay extra for it?
Thanks
The Street CAI comes with a plastic cap on its nosecone. This is the quiet-est option for this kit.
The Noise Baffle is an optional part that you pop-into the Street CAI nosecone if you want it to make more sound yet not be sucking in hot air at lower speeds. It is shown as a $19.44 option on the R60/R61 CAI product page.
The R60/R61 Performance/Track CAI comes with a noise baffle as a standard part. It gets mounted in the snorkel between the CAI housing and the bulkhead.

order placed for the performance/track version
never mind ... i found the buttons to upgrade to the perf/track versionj
thanks Clint
i want the perf/track version ... how do i preorder that?

I'll probably place an order in the morning for the performance version. It's been long time coming, but it looks like it was worth the wait. Hopefully I can get a decent amount for my current VIP intake.
Yup, you can place international orders directly through defendersofspeed.com. You just need to select PayPal as your payment method because of our credit card gateway's policies.
Hi - thanks for the info!!
Is the hole that's cut in the bulkhead for the performance version a simple circle that's cut with a hole saw, or is it a non-circular shape that requires a more complex cut? If the latter, is there a template (instruction manual page or something) to follow? Thanks!
