I bought this intake from New Level Motorsports last week and it arrived the next day from San Diego. Installed it Saturday and took it on a 800-mile trip including about 50 miles of trail driving. I have to say I am impressed. From the comments on this thread I thought it would be much louder than the stock intake. I guess it's louder, but not by much. This is not Infinity FX territory by any means
But the sound is much nicer now than it was before. More throaty and not as constipated sounding.
In line with the "constipated" analogy, the engine doesn't seem to have any more power than it did before, but pushing in the pedal seems to access that power more quickly now. It seems to rev higher sooner for a given gas pedal angle. Its like now that the engine can breathe it can get out of its own way and not act as a damper. Coasting seems improved as well. With the Volant intake, now when you let off the gas pedal the car doesn't seem to slow down as quickly.
I believe that the reduced effort with which the engine sucks in air also resulted in better highway fuel economy. According to EVIC, I averaged 20.4 MPG for that 800-mile trip I took, which includes city driving, climbing two mountain grades at highway speeds, and that 50 miles of "offroad" during which the needle seemed to be hovering around 10 MPG. Now to be fair I didn't do this same trip with the stock intake so it's not a 100% fair conclusion, but during even lightfooted freeway driving during the week before getting the Volant intake, I could only ever get the MPG up to 18.5 for a 30-mile trip.
Overall I'm happy with the product and feel it was definitely worth the ~$300.
