Focus L4-2.0L DOHC VIN 5 (2003)
Cabin Air Filter: Description and Operation
The clean air filter is fitted as standard in most countries. This cleans the incoming fresh air of pollen and dirt particles. It must be renewed after every
40,000 km under normal operation conditions, or after 20,000 km under difficult conditions. If no clean air filter is installed, a plastic grille is fitted
over the air intake. This can easily be replaced with a clean air filter.
