Injen Evolution Cold Air Intake Review:
Injen Evolution Cold Air Intake Review: You hardly notice any difference in sound with a modified exhaust. Turn it off, and the sound is a bit more aggressive. Performance: I did a 0-100 km/h test in roughly the same weather conditions; the best time with the air intake was 7.08. The best time with the intake (without tuning) was 6.66, a difference of 0.42, or almost half a second, which I'm quite happy with. The revs also run a bit differently, and you feel the car has an easier time, and everything runs a bit smoother. Incredible results
