My car was running poorly, had a ruff idle, misfiring and it was throwing fuel mixture codes. I was going to pull the old injectors and clean them then I decided to go ahead and replace them all. The car runs and drives like never before, smooth and powerful.

BMW n54 HIGHLY RECOMMEND!!! I went to the dealer ship they ask me for 6 fuel injector index 12 and for the labor 3850$ but now I spend only 1700 $ for 6 fuel injectors index 12 and for the fuel injector puller and I’m super happy I have saved a lot of money you can change it at home it’s easy just watch some video on YouTube now my car runs smooth I had the old fuel injectors index 08. I’m sorry I know I am not good in English but I tried my best

Super fast shipping, real index 12's! N54 has never ran better:)

Love these injectors. Plus they are the latest version thus far. Then ones I had in my car was Index 5 so yea, big difference.

Fitted a week ago. The car has never run better. Delivery was quick to make its way to Australia. Couldn't be happier.

Very fast shipping with fcp euro and lifetime warranty just love the sound of it, injectors are mounted in my car working like a charm.

I had a rough idle condition which deteriorated into severe drivability issues with the N54 engine in my completely stock 2008 535xi. A check engine light and misfire codes confirmed issues with 2 cylinders. Hoping my problem was something simple (and relatively cheap) like plugs and or coils I first let the car sit overnight, I pulled the coil and plug from one of the affected cylinders and found it was severely fouled and wet with fuel. This confirmed that my problem was at least one leaking injector. When I also discovered that I had a mix of Index 5 and 9 injectors, I decided to bite the bullet and replace all six with Index 12 units from FCP Euro. After installing and coding the new injectors along with FCP's Delphi coil and Bosch spark plug kit my car is running beautifully. Cold starts don't exhibit the roughness they did before and now the idle is so smooth its hard to tell the car is running at a stop light. Power is buttery smooth all the way through the rev range. If you suspect and confirm that you have injector issues with your N54 equipped Bimmer, I would highly recommend the purchasing the Index 12's from FCP they have the best price around and its backed up with a lifetime warranty that no one else in the BMW replacement parts business is offering.

Pricey part in any world made me anxious about the install and quality. The hardware for FCP was flawless. Installed without a bump and coded well. FCP's insanely awesome warranty makes buying anything of value from them a given. No questions. Always.

Great quality!! fast shipping!!

Highly recommend!!
