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 :)
