Really good quality

Got two leaking index 9 injectors. Replaced all 6 with index 12 injectors and N54 is silky smooth again.

After replacing my index 9 with the index 12 car runs great, no more misfires. Coded with protool did the job myself from start to finish in 2 1/2 hours.

Saved +$100 per injector compared to the dealer. OEM as described. About purchase 3 more.

Perfect part Solved skipping problem.

Excellent - Will recommend to any BMWers to order all your BMW parts from FCP Euro for self-learning & DIY (Do-It-Yourself) and never tow your expensive BMW to any BMW dealers, which will avoid excessive non-reasonable & unnecessary expensive charges to fix your cars! All they just want is selling all overprice parts to you with short term warranty, which never fails in their defined warranty time-frame.

Finally fixed idle and stumbling problem I had been having on my 335xi. Got a misfire for cylinders 4&5 one day and had to limp car home. Barely wanted to run and smelt like fuel in cabin. Ordered 3 of these and replaced bank 2. Coded them myself and car now runs great. No issues and easy to install in garage in 2 hours. Highly recommend if your plugs are soaked in fuel and your getting misfire codes and the normal plug/coil change didn't fix. Cant beat price and lifetime warranty.

Had 3 cylinder misfired constantly in bank 2. Ordered the index 12 Injectors from fcpeuro and had them in my hands on 2 days. Swapped injectors and coded them to the car and car is running flawlessly. Thanks alot!

Have been working flawlessly for the last 10k miles. Fixed the misfire issue and my mpg has improved slightly. Couldn't be happier for the price

Ordered my injectors and decouplers from here and couldn't be happier with the service. Got me a Foxwell NT510 to program the flow rates into computer and my all to common missfire is gone, and my 335i runs like new.
