Foam Racing Filters: Dual-layer foam filters designed for motorsport applications where maximum airflow and dirt protection are critical
Pre-Filters & Filter Socks: Protective covers that extend filter life in dusty conditions and prevent water ingestion during wet weather racing
Filter Cleaning Kits: Complete cleaning and re-oiling kits to maintain filter performance and extend service life

Why Choose High-Performance Air Filters?

Factory paper air filters restrict airflow and reduce engine performance. Our high-flow performance filters use advanced cotton gauze or foam media that flows significantly more air while providing superior filtration. The washable, reusable design means you'll never buy another disposable filter—simply clean and re-oil for like-new performance. Most filters show measurable horsepower gains of 3-5% and improved throttle response, especially on modified engines with increased airflow demands.

Filter Types & Applications

Cotton Gauze Filters: Multi-layer oiled cotton provides excellent filtration with minimal restriction. Ideal for street performance, daily drivers, and mild race applications. Washable and reusable for 1,000,000+ kilometres of service.

Foam Filters: Dual-layer foam construction offers maximum airflow for racing applications. Pre-oiled foam traps fine particles while maintaining flow. Perfect for off-road, dirt track, and extreme motorsport environments.

Panel vs Pod Filters: Panel filters replace factory airbox filters for easy installation and stock appearance. Pod filters attach directly to throttle bodies or carburettors for maximum flow and custom intake builds.

Common Applications

V8 engine conversions and performance upgrades
Turbo and supercharger intake systems
Carburettor and throttle body conversions
Race car preparation and motorsport builds
4WD and off-road vehicles in dusty conditions
Street machines and daily performance drivers

Related Performance Components

Complete your intake system with our range of complementary components:

Aluminium Mandrel Bends: Custom intake piping for turbo and naturally aspirated builds
Aluminium 90° Bends: Right-angle bends for intake routing and intercooler piping
Cast Turbo Aluminium: Turbo elbows and transitions for forced induction systems
Clamp Connectors: Secure connections for intake tubing and filter mounting

Filter Maintenance & Care

To maintain peak performance, clean your reusable air filter every 50,000 km for street use or after every race event for motorsport applications. Use only approved filter cleaning solutions and re-oiling sprays—household cleaners can damage the filter media. Allow filters to dry completely before re-oiling, and apply oil evenly to avoid over-saturation that can contaminate MAF sensors.

How hard is it to install these air filters myself?

Installing our high-performance air filters is straightforward—even if you’re new to automotive upgrades. Most filters come with easy-to-follow instructions and basic tools are all you’ll need. Just remove your old filter, fit the new one snugly in its place, and make sure the housing is sealed tight. If you run into any issues, our support team is here to help.

What are the real-world benefits of upgrading to these air filters?

Our Proflow air filters are built for better airflow, which directly improves engine performance, boosts horsepower, and can help with fuel efficiency. Because they use high-flow designs and durable materials, you’ll notice a smoother throttle response, a little extra zip in acceleration, and longer-lasting engine protection—especially on high-demand street machines and race cars.

Are these air filters suitable for harsh conditions or racing environments?

Absolutely! These filters are made with tough, high-quality materials built to withstand demanding road, track, and off-road environments. Whether you’re out for a spirited drive or pushing your custom build at the track, our air filters deliver reliable, repeatable performance and deliver maximum airflow without compromising engine protection.

How do I clean and maintain a reusable air filter?

Our washable and reusable air filters are designed for easy long-term care. Simply remove the filter, gently rinse away debris with water (and mild soap if needed), let it air dry completely, and reinstall. We recommend cleaning every 10,000-15,000 km, or more often if driving in dusty conditions. Proper maintenance ensures optimal performance and saves money over disposable filters.
