What This Product Does

The duct forms part of the air-cooled engine's airflow system, guiding air to the engine fan. Correct duct alignment helps maintain the intended airflow path around the cooling assembly.


Functions

  • Channels air towards the engine cooling fan
  • Supports the intended engine cooling airflow path
  • Replaces a cracked, warped or missing original duct
  • Helps prevent unwanted gaps around the fan ducting


Technical Details

  • Brand: OE Match
  • Reference number: 99310640300
  • Application restriction: Varioram cars only
  • Engine codes: M64.21 / 22 / 23 / 24

Symptoms of Fault

  • Visible cracking, warping or damage to the duct
  • Gaps or poor alignment around the cooling fan assembly
  • Rattling or vibration from loose ducting
  • Hot air recirculation within the engine compartment

Why Replacement Matters

A damaged or incorrectly seated duct can disrupt airflow through the air-cooled engine system. Replacing the affected component restores the ducting arrangement and helps the fan direct cooling air as intended. Inspect the surrounding fixings and adjacent ducting during installation.
