The facts.
DescriptionThe whole story▼
Almost everything sold into an airbox is sold on the promise of more: more flow, more air, more of whatever the standard part was supposedly holding back. The P14 is the item in Sprint Filter's range that goes the other way. It filters finer than the P08 and it passes less, and that second half is not a weakness in the design — it is the price on the label. For a ZT 310-R the only question is whether the air this bike rides in is worth paying it.
Key Features
- Filters at 14 microns — the fine choice for this airbox, where the P08 is rated at 80
- Rated flow of 1,800 litres per square metre per second, roughly a third of the P08 figure
- Dry special nonwoven, never oiled and never dressed, so nothing can be carried off it downstream
- Direct replacement for the original panel; airbox, intake and mapping all stay as they are
- Roughly double the filter area of a typical performance element, which is what makes a fine medium workable in a series housing
- Washed and refitted instead of replaced, with two years of warranty from the date of purchase
Paying in airflow, deliberately
Finer holds back more and lets less through. No medium in the catalogue escapes that, so the whole exercise is choosing where along the line to sit rather than hunting for the best one. This medium sits well down the retention side of it. Measured against the paper panel it replaces, or against the P08 in the same box, its case has nothing to do with how the motorcycle feels — it will not feel like anything, since no drop-in filter adds power to a standard ZT 310-R and this one surrenders headroom on top. The case is about what never reaches the inlet.
When the other element is the right one
If the roads under this bike are swept tarmac, if the year is made of motorway and town rather than farm lanes, gravel drives and construction seasons, then the fine medium is being paid for and not used. That rider is better served by the P08 in the same housing: identical fit, the same washable dry construction, 80 microns and 5,050 litres per square metre per second. Neither choice is an upgrade over the other. They describe different air, and only the owner knows which one the bike breathes.
Care and cleaning
An air line does the servicing: held to the clean side and worked outward, it pushes the load back out of the medium. Greasy rather than dusty build-up washes off with lukewarm water and a little mild detergent, then a full rinse. Drying happens in circulating air at room temperature, because heat of any kind ruins the material, and the SM277P14 is refitted dry and untreated. The maintenance sheet is filed under the Downloads tab.
Fitment & Compatibility
This is the P14 for the Zontes ZT 310-R of 2021 to 2023. Nine Zontes entries in three capacity classes are covered by this one element code; the code and the build year are what to check before ordering.
