说起雷凌和卡罗拉配件，就先来举个例子，聊聊2017款卡罗拉的1.2T发动机的喷油嘴。这款车型是卡罗拉在2016年底中期改款之后发布上市的，也是丰田在中国引进的第二款涡轮增压发动机。代号9NR-FTS，排量1.2T，马力116匹，扭矩185牛米。作为同胞车型2017款雷凌，自然也是和卡罗拉一起更新。
相比以前，喷油嘴是个非常少换的配件，基本不太会坏。不过现在的发动机都慢慢的进化为效率更高的缸内直喷式，虽然效率更高更精准，但是也有缺点，就是比较容易产生积碳。如果使用的油品不佳，就会导致喷嘴严重拥堵。
然后就2017款的雷凌和卡罗拉1.2T发动机喷油嘴其实是用一款型号，配件编码都是一模一样——23209-0Y090。但2017款的雷凌和卡罗拉1.2T发动机喷油嘴价格却是不同的。2017款卡罗拉1.2T发动机喷油嘴价格是1458/个，而2017款的雷凌1.2T发动机喷油嘴只要629/个。2017款的雷凌和卡罗拉1.2T发动机喷油嘴的价格竟然相差两倍还要多。
众所周知，卡罗拉和雷凌其实车型大致相同，雷凌是以美版卡罗拉车款打造的。除了外观设计不一样，其他内核部分，动力系统总成，底盘悬挂构造，电子电器系统都是一样的。
那么为什么2017款的雷凌和卡罗拉1.2T发动机喷油嘴的配件定价会有如此大的差异呢？
其实这不是一次偶然，雷凌和卡罗拉的其他配件，比如减震器，悬挂臂，弹簧，平衡杆球头，轴承，转向节等都是相同配件，比如要挑出10个较为常用的配件，其中几乎有8个都是雷凌的配件更便宜。
这着实让人摸不着头脑。也许有人会问，会不会是雷凌和卡罗拉的产品不一样，卡罗拉用的配件要比雷凌的好。其实这方面没什么可能，首先雷凌卡罗拉的零部件编码都是一样的，这就可以说明雷凌卡罗拉采购的都是同一款产品。而且，丰田的喷油嘴供应商就只有一家，由它的亲儿子电装/Denso供应。而且对于配件供应商，特别是核心供应商的挑选，按照合资公司的模式，我敢说这个权力还是掌握在丰田手上的，也就是他会选定供应商给你，雷凌卡罗拉产品只能从被选定的厂商里采购，所以不存在两家公司采购的是不同产品的情况。
就这种情况，卡罗拉车主们在维修保养卡罗拉时完全可以去广汽丰田的店里做。这两部车确实就是一样的，里面80%的配件都可以通用，而广汽的配件价格较一汽更有优势，在广汽做维修保养还是可以省下不少钱的。
