Review on 63 3084 Performance Intake Kit by Glenn Cho

Performance increase is not noticeable, but the exhaust has not yet been upgraded. sound but. It's a whole different story. Little difference at low revs, which is good because it reduces noise levels. The "beef" only kicks in at over 5,000 rpm. Installing them on your V6 ATS is a surefire way to draw attention, mostly because they already have a pretty unique sound. You'll feel polished and controlled power, not the unbridled, raw V8-powered muscle cars. You may also not notice an increase in fuel consumption. Once you hear the air intake sucking in air, you won't be able to stop pedaling (at least until you hit the speed limit, of course).
