O2Rush Single-Stage Air Filters
Maximum airflow for riders who want every bit of performance

O2Rush air filter construction and features

The O2Rush is Unifilter’s high-flow single-stage dirt bike filter, built for riders chasing maximum airflow and throttle response. Its saw-tooth corrugated foam gives you twice the surface area of a standard filter, so it captures more dirt and keeps breathing freely for longer.

Why riders choose O2Rush

  • Highest airflow of any filter in independent testing
  • Saw-tooth corrugated foam with double the surface area of a standard filter
  • Ultra-soft seals for a tight fit between the airbox and filter cage
  • Available dry or pre-oiled and race ready
  • Designed and made in Australia

Independently tested airflow

In June 2023, Warspeed Industries independently tested seven air filters for the 2023 KTM 450SX on a SuperFlow SF-400 flow bench at 28 inches of water. The O2Rush (O2R1455) recorded the highest airflow of every filter tested, at 223.81 CFM. It flowed more than the KTM/Twin Air OEM filter, Twin Air Beach Race, Dirtlab, Motorex, Funnelweb and our own ProComp2 dual-stage filter.

Test conducted 20 June 2023 at 16°C ambient temperature. Chart axis starts at 215 CFM to show differences clearly.

Which filter is right for you?

Choose O2Rush for motocross, track riding and conditions where airflow matters most. Riding in heavy dust, long enduro days or desert conditions? The [ProComp2 dual-stage filter] gives you an extra stage of protection with almost no airflow loss.

Please note: Dry O2Rush filters must be oiled before use. For best results, use Unifilter Filter Fix air filter oil.
