Well for the temp gauge that actually sound normal. It is supposed to go a little past halfway when the car is sitting at idle and then the fan kicks in.

As for the CAI, I was not aware that Injen made a CAI for any Saturn S-Series and looking at the site, that is most likely a short ram intake they offer.

There are two companies that make CAI for your car. AEM is of course the namebrand one and the other is CP Products. I bought the CP products one not too long after getting my Saturn, which was about 3 years ago. I didn't realize at the time you had to cut away part of the inner fender in order to get the second pipe on. The bend of the second pipe has to stick out of the plastic behind the left front wheel. Anyway, I wasn't willing to cut away my car (first time i ever financed) so I just put on the short ram version and upgraded to the AEM after roughly two years of using the short ram. Both kits are essentially the same, but the AEM tubing diameter is a little less than the CP diameter. I believe the AEM website as well as SPS will have dyno results for the CAI. Power is gained around 3k RPM and you lose power on the bottom end. It has a great sound and you will notice the power (even though there isn't that much of a gain), especially if you have upgraded other essential parts. For example, I also had 2 1/4" diameter exhaust with a 4" diameter titanium APC muffler along with the 92 SC headers (almost just as good as aftermarket header) at the time and my car was pretty loud and was a little more powerful than stock. I say get the CP one if you can find one just because its significantly cheaper than the other and pretty much does the same thing as the AEM version. This generic vs. namebrand idea applies to a CAI for any car for that matter. All in all, either one is basically for the sound and encourages you to go close to redline more often (worth the money either way IMO).
