I only have one data point/experience:
Old forum posts indicated that the E9X Idle Control Device (Valve) (Part # 13417838024) used to cost about $250 each. Now the list price is $742.16. I got one online for $562. I just stopped by the local dealer to get some OEM clamps for installing the valve and their parts guy also said these idle control valves used to be around $250 each. He said he's seen a trend that the parts go up in price as the cars get older. I'm not liking this... Have you seen this trend?
