BMW OE Injector Isolation Seal - Part Number 13537577649

Restore refinement and stop unwanted injector tick with the genuine BMW isolation insert that sits between the direct injection nozzle and the cylinder head. This OE damping element cushions the high-pressure injector to minimise vibration transfer, improve NVH and help maintain correct seating for smooth idle quality and consistent fuelling. Ideal whenever injectors are serviced, removed or replaced.

Why choose this BMW OE insulator

  • Exact BMW fit and material spec for reliable sealing and long service life
  • Reduces injector chatter and resonance for a quieter, more refined cabin
  • Supports precise injector alignment to aid stable combustion and drivability
  • Recommended as preventative maintenance during injector work or carbon clean

We use these genuine parts in our own workshop and customer feedback is consistently excellent, with owners reporting a noticeable improvement in refinement compared with pattern parts.

When to replace

  • Audible ticking from the injector area
  • Rough idle or increased vibration at standstill
  • Any time injectors are removed, cleaned or upgraded
  • As part of routine DI system maintenance to prevent leaks and poor seating
