Fuel Filters: Essential to remove contaminants from the fuel system. Rust and paint chips from your fuel tank can cause premature failure of injectors and the fuel pump. Change as advised according to your car's service schedule; the fuel filter change interval for many cars is every 2 years / 24,000 miles.
Air Filters: Clean air intake is crucial for maintaining power and for the correct, efficient operation of your engine. Change your air filter when it's looking black and worn or caked in dust. If you don't want to inspect your filter, change as advised according to your car's service schedule; likely to be annually, or more frequently if you drive in dry / dusty conditions.
Cabin Filters / Pollen Filters:
