Hi guys, as my title says: I need to find an expansion valve to replace on my acura tl 2003. I took my car to a shop and they said the labor + part would be around $275. The part is $70. I found some websites that carry those parts but I don't know what brand or what type that fit the TL. The technician at the shop told me he doesn't know either (or he doesn't want to tell me), so I really need somebody to help me out. Some recommendations for trusted websites, type of expansion valve, price, etc. Please help me, thanks.
