Description
Unlock measurable airflow efficiency and sharper throttle response with the BMC FM01021 High-Performance Panel Air Filter—a direct OE-replacement engineered for Bajaj’s shared airbox platform across Dominar and Pulsar models.
This is not a cosmetic upgrade. It is a filtration and airflow optimization component built for riders who want cleaner combustion, smoother acceleration, and long-term consistency without recurring paper filter replacements.
The FM01021 is manufactured using BMC’s proprietary Full Moulding technology, meaning the filter element is produced as a single seamless unit. There are no glued joints, no stitched weak zones, and no structural compromises. The rubber frame is molded directly around the filtration media, ensuring a perfect seal inside the factory airbox. That seal integrity matters. Even minor air leaks in traditional filters can allow unfiltered particles to bypass the media. BMC eliminates that risk at the manufacturing stage.
At its core, the FM01021 uses multi-layered cotton gauze filtration soaked in low-viscosity performance oil. This oiled cotton structure allows higher airflow volume compared to restrictive paper filters while maintaining superior filtration efficiency. The cotton matrix is supported by an epoxy-coated alloy mesh, giving it structural stability under pressure fluctuations and vibration.
Filtration efficiency is rated down to 7 microns, whereas most standard OEM paper filters operate around 10 microns. That difference may sound small, but in real-world engine environments it directly influences long-term intake cleanliness. Finer filtration means reduced particulate ingestion. Reduced particulate ingestion means improved combustion chamber health over extended riding cycles.
Where this filter makes a noticeable difference is airflow consistency.
Paper filters restrict more as they accumulate dust. Over time, airflow drops, throttle response dulls, and mid-range performance softens. The FM01021 maintains airflow stability because it is designed to be cleaned and re-oiled rather than discarded. When serviced correctly using a BMC cleaning kit, it restores near-original performance characteristics instead of degrading permanently.
For riders, that translates to:
• Smoother throttle roll-ons
• More responsive acceleration feel
• Improved combustion efficiency
• Reduced long-term intake restriction
• Sustainable reusability instead of replacement cycles
The airflow advantage is particularly noticeable in mid-range acceleration, where intake efficiency directly affects how quickly the engine responds to throttle input. On platforms like the Dominar 400 and Pulsar NS/RS series, which rely on high-revving characteristics and responsive torque delivery, intake consistency plays a meaningful role in ride feel.
This filter is a direct OE-size replacement, meaning installation requires no modification, trimming, remapping, or mechanical alteration. You simply remove the stock air filter and install the FM01021 into the factory airbox. The dimensions are engineered specifically for these Bajaj platforms.
No tuning is required. No ECU changes are required. The motorcycle’s stock mapping accommodates the airflow characteristics safely within factory parameters.
Because the FM01021 is washable and reusable, it becomes a long-term performance component rather than a consumable. Instead of replacing paper filters at service intervals, you clean and re-oil this filter as needed depending on riding conditions. That makes it cost-effective over time, particularly for riders who clock high annual kilometres.
Durability is another advantage.
Heat cycling inside airboxes can degrade adhesive-bonded paper filters. High humidity environments can weaken structural integrity. The FM01021’s molded frame and reinforced mesh design resist deformation under sustained heat and vibration. Whether you ride daily in urban traffic, tour across states, or operate in dusty regional conditions, the structural integrity remains consistent.
This filter is especially relevant for riders who:
• Ride frequently in dusty environments
• Cover long touring distances
• Prefer reusable performance components
• Want smoother throttle without altering engine internals
• Maintain their motorcycles proactively
Compatibility
The BMC FM01021 fits the following motorcycles:
Bajaj Dominar 400 (BS4 & BS6)
Bajaj Dominar 400 UG
Bajaj Pulsar NS160
Bajaj Pulsar NS200
Bajaj Pulsar RS200
Bajaj Pulsar NS400Z
These platforms share a common airbox architecture, allowing cross-compatibility under factory dimensions.
Fitment confirmation is based on shared intake design and confirmed compatibility across the listed models.
Why Upgrade from OEM Paper?
OEM paper filters are designed for cost efficiency and broad durability standards. They are disposable and restrictive by design to prioritize filtration compliance. The FM01021, in contrast, is built for riders who want airflow efficiency without sacrificing filtration quality.
The difference is not dramatic horsepower spikes. It is refinement.
Sharper intake response. Cleaner combustion behavior. Consistent performance across kilometres. Reusability instead of replacement.
In performance tuning ecosystems, intake efficiency is foundational. Even on stock motorcycles, improving intake flow within safe filtration limits enhances the engine’s ability to breathe consistently.
The FM01021 operates within factory tolerances while offering improved flow characteristics. That balance is the value proposition.
Install once. Service periodically. Ride consistently.
This is airflow engineering, not marketing noise.
