They don't use it for the air intake, but for the brakes and air for the driver.
If it's good enough to cool there brakes for hours on end in a race. It's good enough to suck air into my non performance 4 banger.

It should work for my little car!

You are not understanding this. The ripples slow air flow! That's why you don't see rippled CAIs. They use rippled plastic tubing for the brakes and driver because the ripples slowing the air flow don't really make a diffrence. They use smooth mandrel bent tubing on the intake because it does make a huge difference. Use whatever you want on your own vehicle of course but everything I have said is true and can be backed up. :lol:

So your HHR has the same type of hose on it from the factory
Nascar brakes will get more heat in them then our little engines ever will.
I think that my filter box and 2 of those hoses will get lots more air flow than your stock ste up!!!!

A rear end 350 conversion? :confused:

Just showing that other people are using the same stuff that you say is no good!

I know, it helps the vehicle meet emissions. ;) But if I am going to upgrade my intake I am going to put a smooth non rippled evenly bent tube not the same type of restrictive rippled unevenly bent plastic tube. :lol: I am still waiting for a true CAI system for our car because I still am not sold on the these warm air ricer tubes or heat boxes that are out for our vehicle. :roll:

I didn't say the plastic tubing is no good. :roll: You read into it that way. ;) I just said a madrel bent tube would be 1000% times better, which is true and can be backed up. :lol:

Well thats your opinion.
I'm going to do what I want to "MY" car on matter what anyone say's. I think It's going to work good. I don't think that this engine is a big HP maker and I don't want it to be one. I'm happy that you want to spend 200 to 300 bucks on a bent tube. I haven't spend a dime on mine yet. I'm just saying that if GM one of the worlds leading car make and Nascar are willing to use the stuff. Then It should be good enough for little old me.

Back it up then.
I want to see it.

I'd like to see where you get that your smooth pipe is 1000% better.
I could see 10 to 20% better, but not 1000%.
And I'll have 2 of thoughs pipes going to the box. not one like on your factory box.
