请教关于 O2 sensor

[逍遥竹子]

车是Volvo xc 90 2004 T6 前几天做检查发现 Oxygen sensor 坏了，好像是前面右边的，dealer给了我一个part number，我到网上查了一下240左右，dealer这里是400多，不知道我是否可以在网上订了自己找人换，另外就是听说Oxygen sensor坏了一个最好两个都要换，不知道是不是这样的，希望大家帮帮忙，谢谢了

post your part number

dealer 给的part number 是 # 30637519, 不知道这个code 是所有的地方都通用吗？也就是说我在网上按这个code查到的part 就是我需要的 ？

我坏了的时候是从dealer哪里买的part，自己找人换的，这个网站可以买part

Visited www.RockAuto.com before. I will try to buy from them next time. Just found out they have discount on parking brake/hand brake cable, and brake caliper for about 70% off now. Wondering why I never order before...

Now I recall why I never buy from them before. It has 3 warehouses, which will charge upto 3 different shipping cost if the parts are located from multiple locations. All 3 locations are from US, so may need to pay for 20% import custom tax
