if your trying to do it on the cheap just mod the box, you can see how its done and how it sounds in the links in my sig

the heat shield will just reduce the amount of heat soak to the intake element. which should help reduce intake temps and make more power.

whether or not the heat shield genuinely makes that temp decrease your gonna have to do some research around the forums but even then you'd be hard to get a true bead on it because not many of us live in the same area and can do the side by side testing. even then everything about the two cars would have to be the same while testing that aside from the intake. It would be interesting to see though. can the Cali boys help with this one I think a few of you have diff intakes for the comparison? but I know preloader has that cf hood which wouldbe another variable in the equation.
anyway the easiest way to test this would be if a shop tried one, took a reading, then switched out for the other.

Im sure the zzp with that custom heatshield is one nice piece.
Only reason I say ddm is better is that it comes with the heatshield.
As far as the injen goes, looks cool but no thanks

Even without the heat shield, I would still say the ZZP is the better buy. Bigger pipe.
And I'm sure you noted I didn't even bother to mention the Injen.

You guys go through all this trouble just for looks & sounds, this is a freaking Sonic we're talking about, quit kidding yourselves. The stock box works just fine, you're not gonna miraculously gain hella hp from an intake, at least not from our tinyass 1.4L. Hell, even the turbo only gives more tq & not any hp from the 1.8L.

Yep,I would normally agree but when you have facts over text it usually means more and leans towards talking just to talk. The DDM out performs the stock box through the entire power band and add that with improved tuning and you can't go wrong. More power and the sound we want. Now, if we were arguing then Injen intake I would totally agree with you, it's about as useful as a wet fart.
Everyone is of course welcome to their own opinion on the matter, but I do want to put up some data to support that an intake is a good option on the 1.4L Sonics, especially with a tune.
The stock intake does pull air from directly below the fender on the passenger side, which is cooler then the engine bay for sure and it does completely seal the top of the filter to make sure no air from the engine bay enters into the intake. That being said, the stock intake has a much higher restriction when compared to either our intake or the Injen intake, here is a graph showing the difference in restriction:
What that graph shows is that as you increase the flow of air going through the entire intake setup, the restriction increases with all intakes, although the restriction is much higher with the stock setup.
On a tunes 1.4L, this shows up on the dyno, and more power is made at the wheels :
The dark green is our test car with our intake installed and the dark purple line is the same car with the stock intake installed, resulting in a small but also repeatable change in power on the dyno.
As for the heat in the engine bay, of course while sitting in traffic the intake air temps are going to climb, but what we have measured with the heat shield in place, shows that intake temps are usually pretty close to ambient when the car is moving, and noticably cooler then without the heatshield. This is do to a couple of reasons. There is some air that still comes up through the stock intake tube and it is caught by the stainless heat shield we use and therefore goes into the filter. The other reason is that some of the air that comes into the engine bay between the hood and the front bumper is caught also by the heat shield and keeps the intake air temp low.
Lastly, the ECM is very picky about what you do with the intake on this car and most of the new cars out there are also very picky. The way that the ecm is picky though, involves monitoring the fuel trims. Fuel trims are used by the ECM to add or take away fuel so that the ECM hits its target air fuel ratio. Stock fuel trims fluctuate all of the time and are never "0", but instead generally will be less then 10% most of the time when short term and long term fuel trims are combined. So when developing an intake for this car it is very important to monitor the car with the stock intake to see what the fuel trims are, then when developing the intake for the car, make sure the the fuel trims with the new intake do not exceed what they were stock. As long as the fuel trims stay the same or less then stock, the ECM will be completely fine with the new intake and no retune will be necessary.
The cool thing about these little cars is that they are a blast to drive straight from GM, but some like to modify them to make them there own, and get more performance, better looks, etc. It is nice to have some options out there for everyone, and if you are happy with the car the way it comes, that is all that matters.

According SSB you will show zero gains and probably lose tons of power over the far superior factory flat filtered, 2" snorkel'd intake with corrugated rubber for a tube.......
