    Cracked Fuel Injectors

    Guest-only advertisement. Register or Log In now!
    I recently developed some leaks around a one of my injectors. While I examined it I noticed a couple others were. I just replaced all the o-rings and they are leaking just the same.

    It looks like I may just need new injector since I am suspecting they are leaking in the body. Anyone know the cheapest spot to get oem or oem equivalent stock injectors? Looking for a set of 6.

    Anyone use Bosch? Which model is closest to stock?

    How about Siemens?

    stock is Bosch, only difference Audi uses slightly thicker o-rings comparing to OEM Bosch.
    Do not use Siemens on a stock tune.
    Make me an offer, I have a bad engine in Tysons corner, will pull them for you on Tuesday.

    Anyone have experience with a cracked injector? Could it leak more in the morning than after it warms up or would it leak the same any time any temp? I tried soapy water to make sure that's my problem but couldn't tell.

    Thanks V1nny. I am wondering if I need to order the audi o-rings, or get new injectors. Are the injectors you are selling originals or were they replaced ever?

    I haven't been able to find Bosch stock injectors. All I am seeing are the performance upgrade options.
