TTR aluminum intake manifold
 

anyone got this on their HHR? and if so, any better performance compared to the stock plastic piece?
and is this something that can be done at home? (considering that i am not a mechanic and dont really know what im doing, unless there is a How-to)

We actually have only sold this to about 5 HHR members, they do fit, but we have had very limited feed back from HHR specific owners. Cobalt members love these, they are a direct bolt on, you just need to fab up your own intake/tube system, as the throttle body location changes. You will also want a custom tube, to allow for the extra air flow.

If you're not a mechanic as you say and need a how to, well I wouldn't even attempt this if I were you.
If you don't have the know how, then you most likely don't have the correct tools. Let a pro handle it.

hmm bummer, i like trying things thats why, but if like you say its difficult then ill leave it be..
still want feedback from HHR people on here if they've dont it

I think the 2.4 manifold is a direct swap for the 2.2 and flows better.

It has been done, they should post :)
