Filters
Oil, air, cabin and fuel filters for every model - the parts you replace most regularly, gathered in one section.
The four main filters and when to change them
Filters are the most frequently replaced parts on a car - and one of the cheapest ways to avoid expensive repairs. Every car carries four main types: oil, air, cabin and fuel. Specialized ones join them - gearbox, hydraulic and the charcoal filter of the vapor system.
Which one changes when
- Oil filter - at every oil change, no exceptions; an old filter immediately contaminates fresh engine oil
- Air filter - by inspection: a dusty filter cuts pulling power and raises consumption
- Cabin filter - seasonally, or when windows fog up and airflow weakens
- Fuel filter - on the manufacturer's schedule; skipping it costs the fuel system dearly
The automatic gearbox filter is its own story - it changes together with the transmission oil and is often sold as a kit with the pan gasket.
Original or aftermarket
In filters a quality aftermarket part is fully accepted practice - many carmakers themselves fit filters from independent manufacturers on the assembly line. Only two things matter: exact fitment for your engine (best verified by catalog number) and intact, undamaged packaging. A used filter does not exist as a concept - this is a single-use part.
Where to change them
Most filters are simple to change and many drivers do it themselves. For the oil and fuel filters, if you lack the tools and conditions, workshops under scheduled service will help - changing the filter along with the oil is a standard procedure.
