Anyone install Standard Fuel Injectors? (or other upgraded injectors?)

Hey i searched (so please dont kill me for starting a thread) and either missed it or no one has what im looking for.

I have a 2001 330ci (92k Miles) and im thinking of upgrading my fuel injectors to larger, more performance brands. i found these "Auto Part Number FJ663 From Standard"


Anyone know about this product or can point me in the direction of injectors that will perform better than my OEM ones? (they are pretty dirty anyway, so i though instead of cleaning them might as well replace them too some bigger/better ones)


Side Note: im basically trying to bring this engine back to its former glory, the previous owners werent the best (9 shady dealerships got a hold of her before me ) and i want to basically clean out or replace what i can to get it running like new(ish)

No I can't afford to boost it, and idk if they are cheaper than OEM. None have failed. I want to know if "upgrading" them to something other than OEM will be beneficial, I have heard from someone who works on cars (enrolled in ROP program at mechanic shop) that installing larger, performance injecters will help it run stronger (not much, but I'm just looking to have the car perform better)

No benefit at all by just putting larger injectors, you may even decrease performance since everything is calibrated to work properly with the flow characteristics and specifications of the stock injectors. Better clean your existing ones
