Default Yellow STI injectors???

I recently bought "STI injectors" and fuel rail from Nitro Don. I thought they would be pink but they are actually Yellow.


Has anyone heard of these? Can you tell me anything about them?

Try not posting the same topic more than once, and you should have researched your purchase, the pink STi injectors are top feed, the yellow injectors are side feed. The side feed wont work on 02 WRX. Try doing a search.

I am pretty sure they are USDM sti ones then, because they 4 or 5 holes and a aluminum tip like you said.

I still don't understand why the previous owner of my car put 550cc injectors on the car when it should only have like 370cc injectors. It has no engine management either, just a boost controller.
