Well... let me address some things.

#1: I do realise that the CGS is not a true "cold air intake"... I don't think any of the intake options available for the 2.2/2.4 HHRs qualify for that. Obviously most any intake option is going to draw on the warm(er) air from under the hood. It's just a flaw in the design of the vehicle... and there is little that can be done about it.

#2: You can't get the GMPP intake anymore because GM shut that division down as part of their "restructuring" (thank you Gubmint Motors). As far as I have read... after 2010 there will be no "SS" vehicles in GM's lineup aside from the Camaro. The GM performance division that was behind the development of the Cobalt and HHR SS (and all the factory aftermarket parts) is pretty much dead. So the only GMPP intakes you can find now are the ones that happen to be sitting on shelves in a warehouse somewhere.

#3: The other two options... K&N and Airaid both still leave you with that ass-ugly box on top of the engine. Which only serves to interfere with servicing things under the hood. We're not back in the 60's with carburated engines... there is no purpose to having the airbox configured that way... so I'll blame that one on GM's engineers. The CGS intake is really the only option when it comes to cleaning out the engine bay and making things a bit easier to get to in the future.

Again... I'm not expecting any real justifiable gains from putting an intake on this vehicle. The 2.4 with a 4-speed auto will never be fast in NA form... it's a fact of life. However I am after something that looks "cool" and will make things like changing the oil and spark plugs easier in the future.

Joe... thanks for the input. I appreciate seeing some science behind the numbers.

All this said. Has anyone done any real-world dyno testing on the Airaid or K&N? I would love to see their claimed gains vs actual gains.

 

Great observations, Raineman, BUT.....


I think you may have 2 unintentional misleading statements.....as highlighted above.

It's not a flaw in the design of THE VEHICLE. Almost ALL vehicles have the same or similar design. The only "flaw" may be in the initial flow of air when idling at a traffic signal...usually called "the soak" by the engineering community. After several seconds of moving, the air flow begins to lower the temperatures....maybe not what would be realized with a hood or cowl vent, but still lower.

GMPP has NOT been shut down (and remember, these intakes are manufactured by an aftermarket supplier. It just carries the GMPP label. So it's just a matter of placing a release against a blanket purchase order). It was the ENGINEERING GROUP of GMPP that was affected and transferred to other assignments. MOST parts are still available, although some are scarce, probably do to allocation of cash flow more than anything else. Money is usually provided for items of greater significance, i.e, I've been advised that only about 1000 of these intakes existed and sales were slow. That's pretty slim when about 500,000 hhr's exist.

Probably Hyperv6 can provide more info on this.

And remember, these cars were designed as utility serving economy vehicles, with the SS added on later.

As Joe says, just use Loctite for the application.

 

Well, I decided to go with the Airaid. Cheaper than the K&N, and better performing than the CGS. I guess I'll just live with the thing sitting on top of the valve cover.

 

what if you install the filter to the cgs in the ft fender wheel well

 

Here's the Thread On That:

That's where my filter is located.

 

I think if the cost wasn't so high there would have been more GMPP CAI's sold. I know, I know...quality and engineering etc. But it kinda sucks when a friend went to autozone the other day amd bought an intake for his maxima for <$30.
