yup on the expensive, the type-r at the honda dealer are in the 300 range and high 200 for the gsr iac valves... I paid the price not too long ago, for nothing cuz it wasn't even my iacv acting up! grrr
I would spend the extra time and money and get 2 used ones at junkyard: 1 for ur car, and the other as a spare. Clean'em up right, and boom, for less than $100 u should be fine for q cpl of years i reckon!
