Air Filters
Air filters reduce the amount of contaminates entering the engine's parts - Grit, dust, sand, bugs, smoke, soot and oil are butt to name a few of the types of contaminates confronted by drivers in Australia. In order to maintain optimum engine performance, it is imperitive to regularly change your air filter. The Australian environment is one of the harshish on the planet and driving over or through those conditions is a trial for most vehicles. The dust and grit of our dirts and sands are silicone based, containing quartz which is used to abrasives. Quality Air Filters are designed to meet or exceed the OE requirements for Australian conditions and that is why we only source quality air filters from the industry's best, such as; K&N, Baldwin, Ryco, Wesfil, Mann, Donaldson, Uni Filter and Sakura.

Coolant Filters

Donaldson Coolant Filters: Cooling systems are typically partial flow (by-pass) filters, with less than 10% of coolant flowing through the filter. We offer a range of Donaldson filters designed to work in a variety of operating environments and maintenance schedules. Use of the correct filter is important to maintain the proper balance to prevent over-concentration (silicate dropout) or under-concentration, which leads to corrosion, liner pitting and other system problems.


Donaldson coolant filters help keep your vehicle’s cooling system running smoothly. Most systems use partial-flow filters, so under 10% of the engine coolant passes through the filter at any time. Picking the right filter balances the engine coolant, preventing rust, liner pitting, and other damage.

Our range of Donaldson filters fits different use patterns and service plans. You can choose coolant filters for cars and trucks or specially built coolant filters for diesel engines. Each one fits standard housings for a fast, hassle-free replacement.

Coolant filters capture tiny particles that ride in the engine coolant as it moves heat to the radiator. Keeping particles out helps the coolant flow more freely and lets the engine reach its ideal temperature faster. A well-cooled engine can run more efficiently, which may improve fuel economy over time.

When you service your vehicle, remember the fuel filters. Clean fuel keeps injectors clear and ensures smooth combustion. Coolant filters and fuel filters form a strong defence against wear and tear inside your engine.

Donaldson filters meet strict quality standards and are engineered to provide superior dirt-holding capacity compared to many alternatives. That means you can stretch the time between services and spend more hours on the road. Heavy load carrying diesel engine coolant filters perform well under extreme heat or cold, resisting corrosion and breakdown.

Regular filter checks make life easier for mechanics. A clean cooling and fuel systems show leaks or other faults sooner, helping you plan minor repairs before they become major jobs. Small-part replacements cost far less than fixing a seized pump or distorted head.

Every driver and fleet manager should treat these filters as essential gear. Next time you book a service, ask for your coolant and fuel filters to be inspected or replaced. A small step now can prevent big headaches later and keep your engine running at its best.

Cabin Air Filters
Cabin Hepa Filters

HEPA Filters:
High Efficency Particular Arresting filters. HEPA Filters are able to trap as much as 99.9% of contaminates, depending on the filter's MERV (Minimum Efficiency Reporting Value) ratings. The highest MERV rating of 16 is the most efficient. The lowest MERV rating of 1-4 has the lowest efficiency rate.  HEPA filters are composed of a mat of randomly arranged fibers.[16] The fibers are typically composed of polypropylene or fiberglass with diameters between 0.5 and 2.0 micrometers. Most of the time, these filters are composed of tangled bundles of fine fibers. These fibers create a narrow convoluted pathway through which air passes. When the largest particles are passing through this pathway, the bundles of fibers behave like a kitchen sieve which physically blocks the particles from passing through. Western Filters offers superior cabin HEPA air filters, including panel cabin & radial seal, to protect you from pollutants & allergens.

Oil Filters
Oil Filters Keep your Oil Clean ! Contaminates within oil is a major concern for all drivers of all vehicles. No point having a finely maintained machine running using dirty oil. Today’s finely balanced engines, require clean free flowing oil, ensuring clean oil should be one of your top priorities. Soot is generated by the combustion process and forms sludge in the oil.  Lube oil is the life-blood of an engine. It is essential for reducing friction, cooling engine components and carrying wear material and foreign debris to the filter. If contamination generated by the engine is not filtered out, abrasive material will build up and rapidly wear out the moving parts of the engine. Check out our great range. Western Filters stocks a wide range of Oil Filters from MANN, Donaldson, Fleetguard, Sakura, Wesfil and others.
Oil Filters
Oil Filter Caps

Oil Caps are designed to cover the opening used to fill or top up the engine oil supply. Tridon Oil caps are manufactured using either metal, plastic or rubber design depending on the vehicle manufacturer’s specifications. Tridon offers an extensive range of oil caps including metal bayonet, plastic screw and rubber push in designs. The oil cap should be replaced if lost or damaged due to age, heat or neglect. An indication that a cap requires replacement would be the appearance of oil on the valve cover around the filler neck, indicating the cap can no longer seal the engine correctly.

Oil Filter Caps
Transmission Filters

Regular servicing your vehicle's automatic transmission and replacing the filter are your best strategies for maintaining efficient operation and trouble-free driving. At Western Filters, we stock a vast range of transmission filter kit brands, including Direction Plus TransChill, Cooper and DriveTech. If you want to ensure smoother shifting and extend the life of your car's transmission, then replacing your car’s automatic transmission filter is crucial. Fluids, such as oil, fuel, and transmission fluids, are vital for your vehicle's health, and keeping them clean is vital for long-term vehicle well-being. While changing the automatic transmission filter is less frequent than replacing an oil filter, it's still necessary as it can become clogged and less efficient over time.

What is the recommended duration for changing your car's transmission filter? 

It varies depending on the vehicle, but referring to your vehicle’s manual will guide you on how often to replace your car's transmission filter and which transmission fluid is recommended. Typically, car manufacturers advise replacing the filter every few years, typically between 50,000 and 100,000 kilometres, although this can differ. When replacing the transmission filter, it's also advisable to replace the transmission fluid.
