TB45 1998 Fuel injectors

I have TB45 1998. Can you please tell me the original part number of fuel injectors. and how i can check if its original one.

16600-38Y10 you can get them for $14.50 each from AliExpress

I hope the AliExpress ones are good. Once I bought injectors for my 1994 22RE engine on eBay and despite looking original DENSO part, my engine ran like crap. On a injector test bench it was realized that the spray pattern was different from the OEM one. Got a new one from the dealer and the engine was silk smooth again.
