Here's a vid, easier to explain that way lol.


Halfway through my vid you'll see how much the coupler was on that plastic part...I fixed that and tightened the crap out of the other bolts. Hope this stays good
Very helpful, Mike. I see the potential issue, or the potential cause of the issue. Thanks and keep us posted on how you make it on this. I have yet to decide on what I plan to do. Would like to hear from COBB Tuning on this.

I did ping Cobb on this so that they can check in - I am sure they are happy to help!

@B16B ,

I'm incredibly sorry for the intake issue you ran into. It definitely wasn't our intent for that to happen, and we've got a fix in place for you and @02SilverSiHB (who I'll message directly after this)! As many of you know, the last thing we want is for anyone to have a part installed in their car that they aren't over-the-moon enthused about.

For transparency (since this is a public issue at this point :)), with the holiday schedule and the inundation of emails/calls from folks wanting to take advantage of our One Sale, we dropped the ball on timely replies. I take full responsibility for that. We're running at full steam to get caught up. I'm currently having a new intake overnighted to @B16B to get him sorted and up and running. The same will be done for @02SilverSiHB.

Speaking of each of your frustrations with your airbox, these are the only two instances of these failures occurring (that have come to my attention). We are rolling out a new iteration of the airbox (already planned) to all newly built kits that addresses these concerns:
/1/ the looseness of the security bolts on the lower plate
/2/ the MAF housing bolts loosening

For the first part, we've removed the plate entirely, and it's now uniformly carbon. There are no more plate/security bolts. Solved.

For the MAF housing bolts, we are adding in Locktite to prevent them from working their way out. In our testing at the track, daily driving, and on early development vehicles, we never encountered the issue, but as with everything, once it's in the wild under the infinite number of conditions possible, something always finds a way to rear its head ;). The Locktite will ensure those bolts stay tight and secure, keeping the MAF housing flush and attached to the post-MAF hose no matter what you throw at it.

Anyone else get their new box? I got mine, but other than the bottom portion (where I assume water drains) it doesn't look any different. I thought the replacement had the pipe integrated for one whole carbon piece to avoid needing the bolts...but with this new one, it would just move all over the place...am I missing something?

Cobb overnighted me the new airbox with a return label to send the old one back. The new design does eliminate the bottom section
Nvm, I see what he was saying now. It was the lower plate not the other bolts...I'm just supposed to use locktite now lol
I got mine in yesterday, but they sent it with a new MAF housing since my bracket and bolts left the chat.

Hey, all! Glad you each received your new boxes!

Correct - structurally, the only difference is that the plate at the bottom (with the security rivets) has been eliminated. As for the MAF housing, it's secured, just as before, with x3 bolts and Locktite to keep them from backing out.

Don't hesitate to let us know if you have any further questions or concerns!

awesome that you guys took the feedback and did your best to fix it for customers right away! I’m sure it wasn’t easy making the updated ones and shipping them out as soon as possible so thank you for doing that and taking the feedback and improving the product. I will be using your intake 100% when I complete my build among your other parts. Just ordered your RMM also

Ok what am I missing? I'm looking at Cobb Stage 1 vs. Stage 1+ tunes and the only difference in the needed mods is that the Stage 1+ tune uses the Redline Intake. I thought comparing these two tunes might help add some insight into the extra power coming from an aftermarket intake. It looks to me like the Stage 1 with the stock air intake actually makes higher peak and average HP & TQ. So what is the advantage of the Redline intake exactly? It looks amazing, but can I just save $1k and stick with my stock intake? I see a lot threads on how the right aftermarket intakes will net you +10 or even +20 hp, but here is an example that refutes that. I appreciate Cobb posting the values. I sort of wonder if they mistakenly swapped the Stage 1 & Stage 1+ values on their site, but even if that is the case $1k for +5 HP is pretty steep. If I'm completely misunderstanding these tables please let me know because I feel like I have to be missing something.

Hey, @Robo7 !

Great questions, and great callout!

There are a couple of things going on:
  1. The fuel system, from the factory, is fairly tapped out. We're able to eek out a notable bit more power safely and reliably with Stage 1 in comparison to stock. Then, upgrading the intake to Stage 1+SF lets us capture ~5 wHP at the top end, thanks to the improved compressor inlet pressures from the component change.
  2. Our dyno charts don't exactly reflect that, as we used both our FL5 and DE5 interchangeably under different environmental conditions (as we were in the midst of CARB testing). We'll get those charts updated to reflect it accurately with the same car and equal conditions ;)
Let me know if you have any other questions!

Not the greatest before and after comparison, but prior to the Cobb intake with the RV6 660 turbo I made 424hp and 375tq

After getting it retuned, it was evident more fuel was needed, so with the Cobb intake and added Full Race HPFP I ended up with 442hp and 390tq.
