i raced ls1 powered fbodys for years, what ch is saying is facts. although on a 2.4l car i dont think it will make a difference. If you could get a smooth tube to work it would recieve better airflow but its a 150 horse engine it wont pick up that much of a gain. with the ram air fbodys we smoothed out the factory intake air hose/box so it was a smooth straight shot into the intake. the ribbed style tubeing will disrupt the airflow into the engine. (mike from socal should be able to confirm this) dynos have proved this time and time again.

that nascar tubeing that was reffered to is to cool the brakes and driver, neither will gain from a smooth airflow they just need air from the outside, look at prostock intakes smooth and aerodynamic

I agree 100% with every one of Snoopys above statements.

Also, he's not saying rippled will not work, just that smooth is better for a COLD AIR RAM INTAKE SYSTEM. All Formula 1 cars and all the "top end" vehicles I have seen use custom smooth tubing...because of efficientcy
finally some common sense

another thing to consider here is the less connections you make (meaning keeping the number of seperate pieces to a minimum) the better the airflow.

think of it as a airplane fuselage, the less drag = improved airflow

Otherwise any air you are forcing in through the tip is going to be negated by the air being sucked in through the filter itself.
I principle what CH is saying is correct WRT rippled pipe. It is the same as with a dryer vent or anything that requires maximum smooth air flow. The more bends or other "obstructions", the greater the impact on airfow. That said this tends to apply to long runs. The longer the distance the air must travel the more essential a smooth straight pipe would be. For the short distance going from the "ram" point to the filter, I doubt there would be an appreciable air flow difference, particularly enough to affect performance appreciably.

I know what you are saying Crowbar.
If this was such a high perfomance motor I would probally get the CGS.
I'm not using the plastic pipe stuff. I have steel flex pipe to use from the fog light holes to the filter box. It dose have a smooth inside and should work good. I can paint it to.

And as for what CH said about my panties ridding up. Maybe you should get your head out of your _____ CH.....

For everyone else. I'll post pix when it's done and let you know how it works.

Hold on a second. I never said that I had the guts to do it. I was hoping somebody else would so I could see how it looked and worked

Actually, watching the tuners on NOPI tv, I have seen some funky ram air devices on the front of their cars. It would be interesting on the HHR.

Yup
I hear ya Lee.
Ya should go buy a used LS and try it.

How about adding this Airaid-Cold-Air-Intake with a scoop on the hood?

Has anyone put a scoop on the hood yet? If so post some photos...
