Ramair Filters MR-025 Motorcycle Pod Air Filter (58 mm neck ID) – black
Product description
What it is and why people buy it
The Ramair Filters MR-025 is a motorcycle pod air filter designed around higher airflow and strong filtration, using full twin-layer foam. In plain terms: it’s the sort of upgrade people look at when they want their bike to breathe more freely without going down the rabbit hole of complicated setups.
A pod filter like this typically sits where your intake can feed air directly, so the practical question isn’t “is it fancy?”, it’s whether it’s the right style and fit for your specific intake arrangement. Ramair’s key details here are the neck size and the height, plus the fact it comes with a clamp.
The essentials at a glance
What stands out from the spec is the combination of maximum air flow claims with “superior filtration qualities”, backed by a full twin-layer foam construction. Foam filters are a common choice because they’re designed to strike a balance: they can flow well, but the filtering media still needs to do its job.
Two other purchasing realities matter just as much as the marketing language: - It’s specified as 58 mm neck ID, and it’s 85 mm tall. If your current filter/intake uses a different neck size or clearance, this may not be a straightforward swap. - It includes a clamp. That’s one less part you have to source, which can save time and avoid compatibility headaches.
Where it shines in day-to-day riding
If you’re riding with an eye on smooth intake response and you’ve been considering an air filter change for better breathing, this MR-025 is aimed squarely at that middle ground: more airflow on paper, plus filtration that’s meant to be more than “just a sponge”.
On a practical micro level, think about routine access: a pod filter is generally simpler than larger multi-stage intake systems. So if your plan is to maintain the bike sensibly and keep the intake area tidy, a pod-style foam filter can be a manageable option.
What to watch before buying (the honest bit)

This is where it can get a little tricky: the entry gives you dimensions (58 mm neck ID and 85 mm tall), but it doesn’t list anything about the exact fit to specific bikes or intake kits. So you’ll want to double-check the neck size matches what your intake expects, and ensure you’ve got the height clearance where it will sit.
Also, “maximum air flow” is a broad claim. Depending on your setup, the real-world benefit can be more subtle than the wording suggests—especially if other parts of the intake or fuelling are the limiting factor. It’s not necessarily a magic “more power” button, it’s more about making the airflow-and-filtration side of the system work as intended.
Key features that matter (not just buzzwords)
- Full twin layer foam construction: the idea is airflow is supported while filtration is maintained.
- Superior filtration qualities: positioned as better filtering performance, which is relevant if you ride in dusty or variable conditions.
- Complete with clamp: useful if you’d rather not hunt for an extra retaining piece.
- Specified size: 58 mm neck ID and 85 mm tall, which helps you judge fit and clearance.
If you prioritse correct fit and a sensible airflow/filtration balance, these are the details worth focusing on.

Who it’s for (and who should skip it)
It makes sense if you’re specifically shopping for a pod-style motorcycle air filter with a 58 mm neck ID and you want twin-layer foam filtration that’s positioned for maximum airflow.
You may want to skip it if: - Your intake neck size doesn’t match 58 mm (this kind of mismatch is the most common “gotcha”). - You don’t have the clearance for 85 mm height in the airbox/intake area. - You’re expecting dramatic performance changes from the filter alone, without considering the rest of the intake and fuelling picture.

Mini FAQ
Is it a drop-in replacement?
It depends. The filter is specified for a 58 mm neck ID and 85 mm height, and it includes a clamp, but the listing doesn’t confirm which exact bikes it fits. Measure your current setup and confirm clearance.
Does it come with the clamp?
Yes. It’s complete with a clamp, according to the provided details.
What does “twin layer foam” mean for me?
On paper, it’s meant to support airflow while still delivering filtration performance. In practice, it’s about getting a more considered filtration media rather than only chasing airflow.
How do I judge if the 58 mm neck ID is right?
Compare your existing filter/inlet neck size to 58 mm. If the neck size doesn’t line up, you may struggle to fit it securely or may need additional parts.
Final verdict
A solid pick if you’re buying based on the right size—58 mm neck ID and 85 mm tall—and you want a pod filter built around twin-layer foam for airflow and filtration. It’s less convincing if your bike’s intake clearance or neck size doesn’t match, because even a good filter can become a headache when it’s not physically compatible.
