First of all, forgive me if this topic's been beaten to death.

I'm guessing there's more than a few people on this forum that have air intakes installed on their coupes.
To your knowledge, what is the best sounding air intake? Call me a ricer, but sound is my first priority. I LOVE that whooshing noise you get from a proper air intake.
Knowledge of HP gains would be useful as well.

Thank you all very much.

I like how the K&N Typhoon intake sound. Have had it on all my cars

I'm running a Takeda on my 2.5. Has a nice "woosh" around 2800-4500 rpm at a steady (not hard) throttle, loud when you get on it, quiet other than the "woosh" at regular driving conditions. I'm happy with it. I've never heard a bad sounding K&N either though. Sold them for 10 years @ my previous job. So I'd have to agree with SanoSuKe on that also. As far as power gains, you really aren't going to notice anything worth while with an intake (especially on a naturally aspirated engine). The biggest thing I've always gotten is better throttle response, makes the car a little more "snappy" with the higher, less restrictive air flow.

I currently run a Weapon R Dragon Intake on my 3.5 & I absolutely love the sound. I do not really know if it gains anything (short rams usually don't) but it definitely doesn't lose any. It gives it a beautiful throaty sound like a 370z, it looks pretty cool.

Pic of it when i first put it in, I've adjusted it since then but you get to see what it looks like.

I have the Injen short ram. I like it, but honestly I can't tell a sound difference. I got the polished, and notice throttle response and MPG boost. Looks great in the bay too, as I removed all the original airbox housing as well and the closed off channels in the grill (why they made channels in the grill to route air into the airbox then closed off the path I'll never know). Much cleaner appearance.

I also have a catback custom exhaust, so the car breathes better on both sides of the motor. The computer read around 21 combined MPG before the mods, and now sits around 24, while sounding better and being more powerful.

I also have the Injen short ram. There was slightly better sound & no MPG gain, but response was somewhat quicker, & I like the look of it. I later paired it with a Stillen axle-back, & now I'm very happy with the sound & performance. Maybe 2MPH gain. I'm not complaining, I drive aggressively & I'm lucky to get 20MPG in my 2.5. BTW:blaze1808,love the look of that filter shield. http://imgur.com/aymaC5q
