I should had reread your install a little closer. You can actually do the installation without removing the brace or put the brace back in place once you're done with the CAI install. Just be ready to scratch the shit out of the CAI..

Great work and dataset here!

AITs are better than a DCI, but does it flow as well? Would be interesting to see actual vbox comparisons, and/or dyno.

man, this thing was a pain to install with stock DVs. Getting the wheel liner back on was a mission too. I need to get a heat gun to mold the wheel liner so that the bulge that is there now won't rub the tire. At the moment, the faux vent won't stay in and I rub over speed bumps.

Not thoroughly impressed.

you install with stock DVs? I would love too make this thing work, not many ways to screw the install up though. I'm having the same issue as ths guy:

To be honest man it's been almost a year since I installed the thing so I don't remember specifically how to get it in but yes, I am running stock DVs and I remember getting the intake in in <20 minutes. Maybe someone else can chime in? Keep workin' it, you'll find a way. The intake is godly and definitely worth the wait.

I got it to work, I readjusted the pipe with the wheel liner installed. Thanks for calling my install out, I was in finger pointing mode.

sorry i'm late to this thread...but generally if the filter isn't fitting down in the bumper...then in most cases the pipes need to be repositioned. it is definitely a tight fit though...because the filter is soo large.

It is normally that the pipe is in backward. Just takes a little re-positioning normally.

Having the filters out in te open like that, would it cause the car to run at a slightly higher temp??

I did a 40 mile drive on the fwy today and noticed my temp gauge one "tick" higher than I am used to...????

Cold air intake is pointless. Hot or cold air is irrelevant in a turbo setup.

Get an intercooler

You might want to look at the data before making uninformed statements.

Denser air entering the turbo means they can work more efficiently. If the turbo's are breathing in hot air, there is less oxygen so they need to spin harder to meet boost targets. This will cause the turbo's to spin faster, create more heat, and make your intercooler heat up faster.

Sure, your intercooler can cool hot air pretty good, but it's a lot more efficient for power when your turbo's have to spin less and generate less heat to make the same boost. In turn you will make the same power with less WGDC, means less heat generated and in turn your intercooler can get those temps even lower.

Intercoolers are a great option and arguably the better upgrade but in the quest for more efficiency a true cold air intake does have benefits.
