2012 intake manifold

[usa1camaro1969]

It looks to be a composite piece which would be lighter. Any idea if these will swap onto the 2010-11's? Will it move the t/b(concern for any cai).

[Kmorpheus]

From the pictures that I have seen it looks like the Radiator cap is in the middle like the V8's. This would screw Vararam's V6 maybe their V8 CAI, could be used if this is truly where it will be on the 2012 V6

[usa1camaro1969]

I'm more thinking along the lines of if the manifold can be used on the 2010-11's. If you've seen the inside of the aluminum manifold you'll notice the casting seams weren't very clean at all. Then there's the weight of the big chunk of aluminum compared to the composite plastic. Then there's the ease of gasket-matching the plastic compared to the aluminum.

Was wondering the exact same thing

[gahammerle]

I just installed my ported TB yesterday, so it was the first time I took a look inside the intake manifold. Yikes! I would be interested in finding out if the new manifold will swap over too. I'm guessing it would flow better out of the box, but I'd love to see a dyno test with someone running both of them back to back.

[khabboub]

i bet it would bolt right up. i mean doesn't the LFX have the same block as the LLT?

Looks like the mounting pattern is the same

[J.L.TYCHE]

Some of the electronics and vacuume routing is different,Purge solenoid is in a different location

[J.L.TYCHE]

It won't fit,look at the gaskets on the 12 and then the 10

[KMPrenger]

Hrrrmmm...J.LTYCHE.....thanks for those photos! I'm still not fully convinced one way or the other...sure would be great if it did fit though but looks like it may not. (bummer).

If it did, sounds like an easy way for more ponies.

Ya but i think when Tracy is done with our intakes they will be even better.I dont think the weight difference is that big of a deal.

It's more than a weight issue(although those of us 230lbs+ will lose whatever we can wherever we can). If you've ever used a bit on aluminum compared to plastic the plastic is going to be easier to take material. I'd be interested to see a flow-comparison.
From the pics I can't tell if the 2012 is a one-piece where our aluminum one is a two.

[J.L.TYCHE]

Its a one-piece with a small bottom section (ill post a diagram)

Thanks for all the pics, JL

[Ventmaster]

So Tracy's gonna do the intakes next?
Just got the TB today. Time to start saving for the intake manifold now.

And I think you're right Mr.Tyche, looks like the intake runner is a different shape on the '12. Don't think it'll be adaptable for our use.

[BSR-1]

I'm going to port the intake manifold on my 2011. I tried to order a spare so that I could take my time but they're on back order with no ETA.
I'll have to port the one on my daily driver. I think my two days off should be enough time to do a decent job. Should be next week (Monday-Tuesday).

What are the intakes running?
I've got my old one I may be willing to box up and ship. PM me if you want.
My car had 3k miles on it when it was swapped out.

How does one go about porting this intake? What tools and materials are invloved?

[usa1camaro1969]

The dremel has been my tool of choice for years.

There's different types of bits to port/polish. Aluminum tends to go slower as it gums up the bits. When I would work cast iron the bits wouldn't gum up as fast but they'd dull up quicker. The composite would have to be easier.
