BC Girl, you might consider picking up a Cobb short ram or an SPT intake. Both actually work with the car unlike that CAI...

Wich one would you recommend? Short ram or SPT? I drag occasionally, but it's pretty much just my DD until I can afford more mods and another DD.

The SPT is the same design as Cobbs, just with SPT on it. Check for classified listing for eiher of them.

COBB short ram, not anybody else's short ram. COBB and SPT are the only brands to look at.

Umm, I have an AEM and haven't had a single problem with it.

It's been dyno proven to cost you power but that's different than running poorly I guess...

Ever since Prodrive had AEM make their CAI,the AEM ones have been redesigned.Also AEM is now manufacuring parts for SPT.Now which version is on anyones car is a different story but for the most part anyone with the dryflow filter should be good.On a WRX you won't get much more than sound from a CAI but the gains are obvious on a stage 2 STI.Never the less,the MAF signal seems pretty good.Also I have found recently,from spending alot of time on the Opensource forums,the stock MAF scaling has much to be desired with even the stock airbox.With the new MAF and injector scaling tools developed on Romraider it makes it very easy to rescale the MAF (and injectors) and really be able to see data in graph form.Makes it very easy to interperate how much of your scaling is off and where.

Guess I should have been a bit more specific. I have an AEM Short Ram with a Dryflow. Haven't had any power loss that is noticable.

For people into drag racing,a short ram can hinder performance especially durring warmer temps.Unfortunally there have been many cases of detonation (knock) durring the hotter weather because of the increased IAT's from underhood temps.IAT's affect timing big time.So when timing is sky high and you puch it and suck in that burst of hot air,do not expect good things (whether it be performance or knock).The K&N,SPT and Cobb will be the better ones as long as you use the heatsheilds.But the stock box is still better than all of them.It's 100% sealed and made of ABS plastic which is much more resistant to heatsoak than the poo-poo aluminim piping or cats aluminum that most are made of.Cobb I think might be the only one that is made from a resin base.But none of those heatsheilds are even close sealing the intake from the underhood temps 100%.

Is there anything you don't know? I think I'm going to get a stock intake. The Injen CAI I have is short ram I think. How dose humidity affect them?

Sorry, I'm kinda bitter about the whole Americans not knowing shit about the metric system thing. I more agree with the rest of the world that thinks furlongs are a little out-dated.

Humidity affects forced induction vehicles in gerneral not so much intakes.

the SPT's intake has a pretty good heat shield. It's not exactly in engine bay type shorty that a lot of WRX's run. Just staying it's a lot better than most.

Ok, but doesn't the turbo heat the air quite a bit more than ambient temps? Thought that's why we have intercoolers and watersprayers
