BMW X5, 550i, 650i, & More (N63 & S63) Fuel Injector Kit - Specs And Product Review

Blog Feature

BMW piezo style fuel injectors are a very well-known failure item. Failure can happen as early as 35,000 miles or never happen for the life of the vehicle. These injectors aren't a regular maintenance item and don't need to be replaced until notice signs of failure.

This BMW (Index 12) Fuel Injector Kit includes eight new injectors and eight new decouplers that should always be replaced when replacing the injectors. Also included is a new Viton seal with each injector.

To make this job easier, we also sell the Injector Puller and Seal Installer. We highly recommend purchasing this tool as it's nearly impossible without it.

  • BMW X5
  • BMW X6
