My sister's kancil 850 auto, rpm during idling is roughly around 2k without turning on the a/c yet.. i think it is high right? So i'm going crazy to tuning it down n manage to get 1k, i did it but it mess up...
i heard people saying that waja original CAI is supposed to be damn good by itself already.....i still dont know how the mechanism works also....so i just changed to k&n drop in filter...so i was thinking of doing...
