Performance 4x4 High Flow Air Filter – 4" Inlet, Washable, 4-Layer
Your engine is only as good as the air it breathes. The Performance 4x4 High Flow Air Filter is a washable, reusable multi-layer air filter for 4x4 airboxes with a 4" inlet. It’s built for owners who want more airflow without compromising on protection, whether you’re chasing performance on the highway, towing, or deep in the dust.
Multiple layers of coarse and fine filtration media trap dust and debris before it reaches your engine, while the high flow design lets your engine pull the air it needs for better throttle response and consistent performance. Every filter design has been tested in-house on our own vehicles and on our dyno at our Brisbane workshop to make sure it delivers maximum flow.
When it’s due for a service, just wash it in warm soapy water, rinse gently from the inside out, and let it air dry completely before refitting. No expensive cleaning kits and no throwing filters in the bin every service. It’s built to be reused, saving you money over the life of your vehicle. If you’re towing or travelling long distances, we recommend carrying a spare so you can swap filters while one is being cleaned and has time to dry properly.

It suits airboxes with a 4" (102 mm) inlet. If you’re not sure, call our team and we’ll confirm the fit.
How do I clean it?

No. This filter is designed to be used dry, with no oil required.
How often should I clean it?
At each service interval, or more often if you’re driving on dusty roads.
Should I carry a spare when towing?
Yes. For towing or long trips we recommend a spare so you always have a clean, dry filter ready to fit.
Will it last forever?
No. All filters, whether single-use or cleanable, have a life expectancy. It’s time to replace your air filter if it starts to deform or crush in, if visible debris can’t be cleaned out, or if you notice a loss in performance.
