I removed the current injectors from my gen 3, I think one or two are shot and are not closing properly plus they all need cleaning too, the injectors are Denso 195500-4370, however, searching online (especially on aliexpress) reveals that the Denso part is just a rebrand of chinese made injectors? Am I correct or are the ones on aliexpress knockoffs of the Denso ones? They share the same part numbers. Any advice on this topic would be helpful. Thanks.
