UNIfilter Pre-Oiled Foam Filter – KOVE 800X (all models)
Desert racers have been relying on these reusable foam air filters from UNIfilter for years. No paper filter can provide the same amount of protection in the dirt. Additionally, UNIFilter manufacture filters for KTM, Yamaha and Suzuki.
The filters can be washed and re-used pretty much indefinitely, keeping your engine safe and letting it breathe to its maximum potential.
Specifically for the KOVE 800X we have incorporated a metal perimeter frame. This ensures that the filter does not deform when inserted into the airbox, (unlike standard filters) which can otherwise cause potential dust intrusion at the base of the filter housing

Revolutionizing Motorbike Performance: The Ultimate Guide to Enhancing Engine Protection with Advanced Air Filter Technology
Single stage CNC Profile Cut Saw-Tooth Design Foam:
- This innovative design feature enhances the air filtration efficiency of the motorbike’s air filter. The saw-tooth pattern increases the surface area of the foam, effectively trapping more contaminants and particles from entering the engine.
- Compared to standard filters, this design offers double the surface area, ensuring superior filtration performance and optimal engine protection.
10-15mm Profile Foam Thickness:
- The foam thickness plays a crucial role in filtering out unwanted particles while allowing sufficient airflow for the engine’s optimal performance.
- With a thickness ranging from 10 to 15mm, this air filter strikes the right balance between filtration efficiency and airflow, ensuring maximum engine protection without compromising performance.
Polyurethane Grommets:
- Polyurethane grommets provide secure and reliable attachment points for the air filter, ensuring a snug fit and preventing air leaks.
- These grommets are durable and resistant to wear and tear, offering long-lasting performance even in demanding riding conditions.
12mm Ultra-Soft Foam Seal:
- The ultra-soft foam seal ensures a tight and effective seal between the air filter and the air intake housing of the motorbike.
- With a thickness of 12mm, this foam seal minimizes the risk of air bypass and ensures that only filtered air enters the engine, optimizing performance and protecting against contaminants.
Laser Cut Fitment:
- All filters are precisely laser-cut to ensure perfect fitment and compatibility with the motorbike’s air intake system.
- This precision manufacturing process guarantees a seamless installation experience and eliminates the need for modifications or adjustments, saving time and effort for the user.
Flexible Glue Seams:
- The use of flexible glue seams prevents the air filter from becoming brittle and cracking over time, ensuring durability and longevity.
- This feature enhances the overall lifespan of the air filter, providing consistent performance and reliability throughout its service life.
- These points highlight the key features and benefits of the air filter, emphasizing its superior design, construction, and performance for motorbike enthusiasts seeking optimal engine protection and performance.
How 02Rush air filters compare to the competition.
In the dynamic world of dirt biking, one component often overlooked yet crucial for performance is the air filter. A test focused on filters designed for the KTM 450SX 2023 model. Conducted at an ambient temperature of 16 degrees Celsius, the examination utilized the Superflow 400, a trusted tool in the industry, at a pressure of 28 inches. Independently overseen by Warspeed Industries, the test aimed to gauge airflow and filtration efficiency.
Results showed significant variations among the filters tested. Some demonstrated superior airflow characteristics, potentially enhancing engine performance by facilitating optimal air intake. Others, however, revealed limitations that could compromise engine efficiency.

In conclusion, this test highlights the importance of selecting the right air filter for dirt bikes. By understanding the performance discrepancies, riders can make informed choices to elevate their bike’s performance and durability. Ultimately, the air filter plays a crucial role in maintaining engine health and maximizing power output, making such tests invaluable for riders seeking peak performance.
About UNIFilter
UNIFilter Australia is a totally Australian-owned family company business.
- The company commenced operations in 1976 as an importer of motorcycle air filters and components.
- In 1988 the company commenced production in its’ then Sydney factory.
- By 1991 it had outgrown the original Sydney factory and moved the operation to Hornsby.
- In 2006, again the production had outgrown the factory and warehouse.
- So the production, warehousing and administration was moved to the New South Wales Central Coast into 2 purpose built factory units.
- Today the production is operated using state of the art CNC laser and router equipment. This allows us to provide not only our “Unifilter” brand. In addition, we also supply original equipment filters for Yamaha, Suzuki, Nitto, Stihl and KTM.
We are a company proud of our capabilities, providing not only manufactured air filters but providing design and technology for many automotive and industrial companies. We only use premium raw materials in our manufacturing process. Moreover, wherever possible we support “Australian Made” in our materials and packaging.
