    Best Fuel Injector Replacement

    I'm looking to replace my injectors and was curious what you guys think would be the best replacement for a stock M20B25. All the big suppliers list these: https://www.fcpeuro.com/products/bmw...injector-62415 as the new replacement part but they don't really look like the og ones. Besides the $200 (a piece) genuine BMW ones I'm seeing rebuilt ones from GB Remanufacturing as an option which look like originals. What would you go with?

    If those are close to stock flow rate they'll be fine my quick research found 15.4lb/hr which is ok. These will mount up ok and are preferred over the old metal body ones. pretty good price for a new non copy injector

      How do you know you need new ones. I us "Sea Foam" couple times a year to clean up the fuel system.

        Thanks, I'll go ahead and give them a try.

        I don't for sure but my car has 190k on the original engine and I'm assuming original injectors. The car runs fine but not as smooth as I'd expect. I've replaced all ignition components, ran injector cleaner, no vac leaks, various sensors etc. I don't mind dropping a couple hundred if it helps the car at all.

          I've had lack lustre results having injectors cleaned and they simply don't last forever. If i recall a few people have had issues on these forums or others with them sticking open or closed after getting them refurbished so from a preventative maintenance there are worse things to spend money on.

            I would recommend the injectors you linked. We install those often here.

            They are the updated version which is why they don't match the original in appearance.
