Air Intake Kit?

[jhmcmath]

I've heard from a reputable dyno shop that the EVO intake system is good for 3-4 HP at best. I just tried to have one installed last weekend but my mechanic lacked some screws that were supposed to be sent with the kit but were not. He did de-snorkel it in the process and the sound is much improved. Curious from those who know how much better the sound is with the kit installed than with just de-snorkeling it. Combined with a B&B sport muffler, it's starting to sound like a real sports car.

As pointed out in other threads, this is really seems to be a relatively expensive mod to just get more sound out of the motor. Given that my car was so quiet when I first got it that I sometimes thought the engine had stalled at a redlight, I'm happy to be able to capture some of that 911 style roar when I jump on the throttle.

At this point just wondering if it's worth going ahead and installing the EVO intake or just leaving it de-snorkeled as is.
