Sounds stock haha

Hmmm I'm thinking I might like the FSWERKS intake better. Hard to tell at this point

I'm debating if I should purchase this intake and do a Hybrid Cobb and Mountune intake.

Or buy the FSWERKS one and make a hybrid. Its on sale. I'm also considering it, One idea: Cut the FSWERKS tube right in front of the sensor, then add a silicone coupler, rotate the end, insert it into the mountune box through the opening, and use the FSWERKS cone filter.

If nothing else, I'm going to insulate the Mountune box with thermal shield in an attempt to reduce heat soak. I like the idea of using the OEM box, taking a FSWERKS intake, and making the end fit into the top of the airbox that has a hole cut into it. If I could do it on the sly, I'd have a plastic one made on our 3D printer.

CP-e is producing another alternative in the near future that has the Mountune snorkel and an enclosed box.

Exactly what I wanted to hear. Intercooler and intake pakcage is on the list!

sounds pretty good. ill be interested in the stage 2 kit around xmas. minus the AP

that sounds like a great idea

Why is it 3" ? The turbo inlet is 35mm, there is no reason to use anything bigger than 1.75" piping to it...

Lmao. Just kidding. Looks really nice. I'd like to have it
Glad cobb finally has the packages released

Guess that begs the question (rhetorical) as to why then was the stock intake tube designed to start out with a ~2.5" diameter tube to begin with?

Recieved my Cobb CAI last night...they really did do a great job on the fabrication...

Many have questioned the inlets need or lack of need for a larger inlet. I say... If your increasing from 2.5" to 3", why would you not want to increase from the turbo to the intake from 1.3" to 2.5" faster, nevermind the fact its on a 90 degree bend as well.

I understand velocity is important as well, but if air speed was everything, we wouldn't be going from a 2.5" intake to a 3" intake.

Restriction is real. Bigger = more flow. Shape means a lot too. Who's right? I have no idea. But I'm not sticking a bottle neck right in the middle of the system and hoping for the best...

Why is the turbo outlet 3 1/3" and the cat outlet is 2.27" ? Must be for "velocity", so why would we change it? Hopefully we can find some 3/4 exhaust tips to REALLY speed the air up and make more power, lol.

Back on topic sorry. Prob the wrong time and place

I do think this is going to be the best all around intake. I can't wait to hear what everyone says about it.

Crazy that the lower box isn't a restriction though, it only has the small little duct on the front to feed it air. But if cobb say's its good, then.. I'm on board.

Very much so, he even stated his question was rhetorical.

Guess that begs the question (rhetorical) as to why...

Yes indeed as the rhetorical question I previously asked wasn't looking for an answer....just some thought......

And "gradually" reducing the diameter of the intake tube as it nears the turbo inlet port is where you get the velocity kick needed....It appears that the current stock tube that attaches to the turbo is very well designed with a gradual decreasing diameter to accomplish this as any abrupt stepped changes this close to the inlet could cause an undesirable destructive turbulence effect...Of coarse a larger turbo with greater dia inlet port would need a careful redesign of the short tube...

I looked at the stock airbox's outside air duct (oval) and it appears to have an "equivalent" cross sectional area compared to the rest of the Cobb 3" intake system...And I don't see the stock box itself adding any additional restrictions...It appears Cobb's engineer's really did think this one through...

And I do like that idea that I don't have to worry about upgrading the CAI any further once I do get around to upgrading to a larger turbo...

Also I assume Cobb has taken into account the 3" diameter when they were developing their stg2 & 3 tunes which had their CAI installed at the time....

edit: Cobb's CAI tube ID measures ~2 5/8"...and OD is ~3"
