Cold air intakes

I was looking into purchasing a cold air intake for my 09 wrx 265. Any one have some suggestions? So far i have been looking at a Weapon-R or a Perrin.

I've never understood why anyone would want a hot-air intake. Is the sound really worth the performance you sacrifice ?

Is there really that much performance lost? Yes, Ive herd of people losing a lot of power with cheap $30 intakes or intakes not made specifically for Subaru, but you get what you pay for...or if you dont do your research...

It's pretty simple. The lower your intake air temp, the more power your engine makes. Drawing air in from under the hood right above hot manifolds and the UP is going to be substantially hotter than the route the stock set-up uses, drawing air from under the hood, through the fender and panel filter.

Yes, of course the turbo is heating up that intake charge, but if it starts out cooler, your ahead of the game. A larger TMIC or FMIC can make up for that. One other solution is to extend the CAI with 3' ducting and put the cone filter down in the bumper and use your fog light opening as an intake duct, but you sacrifice your light to do it, and the filter will get filthy fast.

Well I guess if you take it to a track or whatnot its a totally different thought process since all I do is have grove roads to drift around in and no professional tracks or dynos. My cobb sounds better and looks cooler and just makes me feel better lol so it works for me.

Not to mention the IAT sensor is located in the MAF. This temp reading affects timing,boost and fueling compensation tables.
