Ramair Filters MR-003 Motorcycle Pod Air Filter (40 mm neck ID) in Black
Product description
What it is and what it’s for
The Ramair Filters MR-003 is a motorcycle pod air filter designed to replace an existing intake filter on a bike that takes this style of “pod” element. In plain terms, it’s aimed at riders who want to improve how the engine breathes compared with a more basic setup, while keeping filtration in mind. It’s the kind of upgrade you’d look at if you’re already thinking about intake efficiency and want the filter to do more than just sit there.
On paper, the pitch centres on maximum airflow, with “superior filtration qualities” and a full twin-layer foam build. There’s also a clamp included, which helps if you’re doing the swap yourself.
What stands out in use
If you’re chasing a freer-flowing intake, the MR-003’s construction and airflow claim is where it earns its keep. The full twin-layer foam construction is the detail that matters here: foam can be designed to support airflow while still catching dust and debris before it reaches the combustion area. That’s not a guarantee of performance on its own, of course, but it’s a coherent approach for a pod filter.
The other practical bit is the form factor: it’s specified as 40 mm neck ID and 70 mm tall. That matters because pod filters can vary a lot in fitment. If the neck size and height match what your bike’s intake expects, this becomes a straightforward replacement-type job rather than a “make it fit” project.
Here’s a realistic micro-example: you’re doing a seasonal maintenance session, pull the old element, clean the intake area, and slide the pod in, tightening the included clamp. If the fit is right, you can go from “filter change” to “ready to ride” without needing extra hardware.
Key technical details to check before you buy
The listing points to these specifics, and they’re worth treating as non-negotiables:
- 40 mm neck ID
- 70 mm tall
- Full twin layer foam construction
- Complete with clamp
- Maximum air flow and superior filtration qualities (as stated)
If you’re buying for a known setup, measure twice and compare the neck diameter and overall height against what your intake uses. It might sound obvious, but pod filters live or die by fit, and it’s easy to end up with something that physically doesn’t seat properly.
Who it suits (and who should be cautious)
It’s a sensible match if you want a pod filter that leans towards airflow while still being a foam element built to filter properly. You’ll likely appreciate it most if you’re doing routine maintenance and want an upgrade that still looks like it belongs in the intake system rather than turning the job into a fabrication exercise.
It may not be the best choice if your priority is a drop-in replacement with zero checking required, because the 40 mm neck ID and 70 mm height suggest compatibility is specific. Also, if your bike’s intake setup requires a particular sealing arrangement or different dimensions, this could end up being more hassle than it’s worth.
Pros and limitations
Why people consider it: - Foam construction with a twin-layer approach, aiming to balance airflow and filtration - Maximum airflow is part of the stated goal - Supplied with a clamp, which removes one common “what else do I need?” headache - Neck ID and height are given, which makes fitment checking more reliable
Things to keep in mind: - The listing doesn’t spell out flow testing results or real-world gains, so the performance benefit is best seen as “based on design intent” rather than proven figures - If your intake doesn’t match the 40 mm neck ID and 70 mm tall dimensions, it may not sit correctly
If you’re comparing against the most basic replacement filters, remember those are mainly about maintenance and dust protection. This one looks more like an upgrade path where you’re willing to pay attention to fitment and airflow goals.
Is it worth it?
If you’re buying a motorcycle pod air filter and you already know your intake uses a 40 mm neck ID and around 70 mm height, the Ramair MR-003 makes solid sense on paper. The inclusion of a clamp and the twin-layer foam construction line up with a practical “upgrade while you maintain” approach.
You should consider skipping it if you don’t have confirmed fitment for the neck diameter and overall height, because pod filters can be unforgiving when the dimensions are off. It’s also not the place to expect specific performance numbers from the listing alone—think of it as a design-led upgrade, not a miracle mod.
Mini FAQ
How do I know if this pod filter will fit my bike?
Start with the 40 mm neck ID and the 70 mm tall measurement. Compare those against your current filter or intake requirements.
What does “twin layer foam” mean in practice?
It suggests the foam is built in two layers to support airflow while filtering particles, rather than acting as a single, simple layer.
Does it come with the clamp?
Yes—it's listed as complete with clamp.
Will it definitely increase performance?
The listing focuses on maximum airflow and filtration quality, but it doesn’t include measured performance results. Real-world gains depend heavily on your bike’s setup.
What should I do before installing?
Check the physical fit first (neck size and overall height), and make sure the intake area is clean so the filter seats properly.
