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

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.
