I've searched and never got a clear answer.

Will a 2.4L intake mani from a 2008, fit my 2008 LS.

What do I need?

All I got from searching is that the 2008 is different than previous years and something about not needing some adapter.

Clarification = brownie points!

 

Yup. I did it. I think I have an 07 2.4L manifold though. All you need is the manfold, about 3 feet of 1/2" brake booster hose, some hose clamps, and the gaskets if you want to replace them (I replaced all my gaskets). The 08 TB bolts right on to the 2.4L manifold since its got an extra bolt hole.

 

Is there a complete kit I can buy with all the ****?

CED says the 08 isn't tested yet, where would I buy a 2008 2.4 mani kit?

 

The CED kit fits the 08, you just don't use the TB adapter that comes with the kit. But it's WAY cheaper if you just buy everything from gmpartsdirect. I think I spent $125 for the manifold and $15 for gaskets. Plus maybe $5 for the hose and clamps from NAPA.

BTW do you like you Injen CAI? I'm thinking about upgrading if I can sell my K&N.

 

yes the 2.4 mani will fit the 2008 cobalt and i think the gains are pretty well IMO. definetly get the kit that comes with all of the gaskets just in case you take a old one out and it rips. as for the injen cai, i have one of those as well and its a beauty i love it! get the SP version or the newest one for the cobalts it may be the only one actually.

P.S. word of advice by the way... definetly get a hydroshield for your filter trust me its a good investment!

 

Has anyone dynoed the gains on the 2.4 IM?

 

sry.. no dyno proof but its definetly something that feels a little quicker specially after 4K because the powerband gets pushed back a little.

 

how much u want for ur CAI?
and yea the 2.4 is a direct bolt on and its supose to give ya about 10hp

 

Someone on the j-body.org found aftermarket 2.4 Cobalt manifolds for $30 a piece, yes... $30 a piece. I am skeptical but the guy says they are legit as he bought one and has one in his possession. Don't ask me how they can afford this.

People are popping them on their Sunfires and Cavies.

 

Duplicate, please delete.

 

*******, I'll check out gmpartsdirect.com thanks!

BTW, Injen = WIN!

It rains like ******* crazy our here in Chicago and no shield for me.

 

i've been on my injen intake 4 years in the chi no shield. anyway the injen can convert to sri if you're really worried.

 

Ya it can convert into the short ram as well sorry i forgot to throw that out there, i must have just hit a big puddle then or something because my intake was soaking one time comming home from school with the cold air set up.

 

Ya, if it rains real bad mine will get water on the filter because of the retarted fitting of the front end of these cars, aka, between my headlight and the bumper.

Back on topic, I don't need a 2008 2.4 manifold right?.. And it will bolt right up? Bolt for bolt?

 

Bump.

 

You can get a 2007 2.4L Manifold. It will bolt right up.......bolt for bolt. You will need to drill out the MAP sensor hole a little bit to get the MAP sensor to fit. I forget exactly how much. It's on here somewhere......MAVEN did a how-to on installing the 2.4L Manifold on a 2.2L.

 

Ah, damn, I hate having to **** with ****.



Some dude said some of the bolt holes don't line up and you will have an empty hole.. I was like WTF..

 

its much cheaper to buy it separate.. mine was an 07 2.4 mani and it fit into my 08 2.2.. i reused my gaskets and all i needed was a foot and a half of 3/4 brake booster hose, and the transfer vent seal which was 12 bucks, plus u gotta to a little manual labor to widen out the MAF sensore hole.. i used a dremel for that

 

Roughly 200 from gmpd for everything you need I think (for an 06). If you dont need the plate may be closer to 160-70 range for ya.CED drilled the hole for me
