The median asking price for a used one is $169.99, across 30 live eBay listings for the 2003–2003 generation. That is what sellers are asking, not what buyers paid. Sold prices are not published in a form anyone can measure at scale, and an ask read as a sale runs about a quarter high — so this says which one it is.
That depends on what the yard charges for it and how long it takes to get off the car, and on where it sits against the other 13 parts on a 2003 Acura Rsx that have a market. The full sheet for this vehicle ranks all of them by what you save and by what you clear.
