    I think you can buy them separately. If trying to get them from Tischer, you just have to explain to them that you already have the other 2 in the bank as the same revision as the new one. Tischer will try to sell you three at a time though, stating the official BMW policy that the injectors cannot be mixed in the same bank of cylinders.

    I don't understand what you mean by this? You always have to register your new injectors. Otherwise misfires will occur, especially under high boost. There is nothing different in the registration procedure between the "old" and the "new" injectors.

    FYI....Just got off the phone with Rockauto parts and they have the 079 injector for $92.79. Their part number is FJ1050. If installing one at a time works, i might go this route. I am currently experiencing rough idle and misfires on cylinder #3 . Tried swapping coil and new spark plugs and still get cylinder #3 misfire on cold startup. Any update on the logs with mixing the new style injector with old?

    I would HIGHLY recommend against it.


    Those are not OEM injectors, but looks like they are "rebuilt" from "standard" motor products.


    I went through 18 fuel injectors from Rock Auto for my 6.0 ford diesel, remanufactured by SMP.
    I went through HELL with rock auto when I installed 8, and 4 didn't work.
    I ordered 4 more, 2 of those didnt work. (notice: I said ORDERED- as they wouldn't send out replacements until they got the "Defective" ones back- meaning 1 week+ down.....I use this truck for business and had no other choice but to buy 4 more)
    Two of the 4 were dead when installed, I ordered 2 more, one of the other ones died.
    I then pulled them ALL out and went with another company for 8 injectors- installed them and was done with it.


    Rockauto can KISS MY ASS. I was over 8100 in credit card charges with them.


    Mind you- 6.0 injectors are 200 bucks each, with a 250 dollar core charge...... plus shipping- plus pulling the injectors out of my truck 26 times total..... It wasn't worth the problems/issue/hassle/money/frustration/time


    SMP stood behind their products after rock auto giving me the finger, and refunded my money after testing the injectors themselves (which they only found 3 out of 12 bad, but under boost more would die on a power balance screen).... and for that, i really appreciate- but rock auto STILL owes me a refund on one injector and core- which never happened and im too pissed to argue with them.


    your mileage may vary- but just get a REAL OEM injector from the dealer.

    I sell them for 180, including the seal ring.

    I would have to agree with this assessment of Rock Auto, although my experience wasn't nearly as bad. I purchased two ignition coils from them and they feel so much cheaper than the OEM Bosch units. Installed it on the cylinder I was getting the misfire on (even with a new plug) and the misfire still happened. Swapped the coil with an OEM coil I purchased from another vendor and the misfire went away.

    I concluded that Rock Auto is cheap for a reason. You're likely to get what you pay for. For some things I'm sure they're fine, but for ignition and fuel injection components I would stick with OEM.

    well, you guys have convinced me. I will not be buying from Rockauto. I'm anxious to see if vasillaluv has had any issues with mixing new style with old in the same bank.

    I have bought parts from Rock Auto. Never for the BMW but for other cars. I have been pleased with the quality of the parts. I was even able to return an order of shocks and struts that I decided not to use. You really have to pay attention to the manufacturer of the products. Rock Auto is just a distributor.

    There are some things, however, like injectors and ignition coils, which I would only buy from the dealer or the OE supplier (Bosch, VDO, Siemens, Continental, etc.). You just have to be careful and when in doubt, go with BMW branded parts because they are staking their reputation on them.

    Just want to share a few photos of spark plugs and get some opinions. These spark plugs have about 100 miles on them and were replaced after having misfires on several cylinders. Misfires went away, but misfire on cylinder #3 persists. This misfire only occurs on cold start. So, I decided to take out the spark plugs and noticed carbon build up on spark plugs from cylinder numbers 1 and 6, but nothing from cylinder #3 . Also the carbon deposit is only located on one side of the spark plug and away from tip, near the threads. Is it possible to have a leaky injector and not show carbon on the spark plug.

    I am a bit confused. If anything, I should be getting misfires from cylinders 1 and 6.

    Is it possible that the plug you pictured was not torqued down sufficiently?

    I used a very old torque wrench....not sure if its calibrated well. What can happen if not torqued exactly to spec?

    Car runs great. I've not logged anything yet, but the engine runs super smooth and it sounds and feels happy.

    Since the tip and electrodes looked good, I was speculating whether the carbon on the threads was deposited there cause the plug wasn't tightened down sufficiently and some exhaust gas got past the crush washer onto the threads.

    Just a theory.

    Well, I just went ahead and purchased one 079 injector. As soon as it arrives i will install it and code it. I Hope I have the same luck as vasillalluv.

    sorry to kinda hijack your thread but my #6 smelled gasoline and was a bit wet (not oily wet, just gas). Injector leaks? Valve Gasket leak?

    The general agreement is that if your spark plugs are wet from gasokine, then the injectors are leaking. In fact,when customers take their cars to the dealer for rough cold starts with misfires, the first thing they check are the spark plugs. If they find them fouled with gasoline, they advise to replace the injectors.

    I get mine to misfire if I drive it like I stole it first thing in the morning. If I don't push the car it does not store a misfire code. That's how I was able to figure out which cylinder. Interestingly, having e85 in the tank made it worse also.
