What it is

The Worcester Bosch resonator air intake Mk1.75 is a moulded air path component that sits in the combustion air intake side of the appliance. It shapes and smooths the incoming airflow and damps induction noise from the fan assembly, so the boiler runs quietly and the air/fuel mixture stays consistent. This is the current Worcester Bosch part 87186630720, listed under pipes and hoses.

Signs this part needs replacing

  • Whistling, droning or booming noise from the air intake side of the appliance
  • Cracks, splits or perished material on the intake pipe or resonator body
  • A loose or poorly seated connection where the intake meets the fan or air inlet
  • Distortion or damage found during a service or after work in the combustion air path
  • Combustion readings that cannot be brought into specification because of an air intake fault

Before you order
