Revitalize your BMW's performance with NGK's Original Spark Plugs, designed to address common issues like poor idle, reduced fuel efficiency, and engine misfires associated with worn-out spark plugs. These NGK plugs offer a solution by preventing electrode wear, which causes an oversized gap and weak sparks over time. They effectively tackle carbon buildup issues that can bridge the gap and hamper performance. Replacing worn-out plugs with NGK aftermarket units restores power, enhances fuel efficiency, and ensures a smoother idle for optimal engine performance.

Product Benefits:

  • Resolves poor idle, low fuel efficiency, and engine misfires
  • Prevents electrode wear for consistent spark
  • Reduces carbon buildup for improved performance
  • Restores power and fuel efficiency
  • Enhances engine smoothness and responsiveness
  • Ensures better harmony within the ignition system
  • Unlocks hidden horsepower and raises fuel economy

This is an OEM MAHLE fuel filter that removes dirt and other particle contaminants from your fuel.

A clogged fuel filter makes it difficult for your engine to get all the fueling it needs. Filters commonly clog from a deteriorating gas tank, bad fuel, or other debris in the fuel system. A fresh fuel filter addresses many fuel related problems including surging, stalling, cold start issues, and poor performance under a variety of conditions.
