The facts.
DescriptionThe whole story▼
The 14-micron mat is listed for the G 310 R and the Apache RR310, and not for the GS that shares their airbox. That looks backwards until you consider what the medium is drawn against: not the coarse grit thrown up by a gravel track, but the fine suspended material that hangs in air — which is as much an urban phenomenon as a desert one, and which a commuting roadster meets every working day.
Key Features
- Dry special nonwoven filtering at 14 microns, rated at 1,800 l/m²/sec
- Depth filtration, holding the load inside the mat rather than only on its face
- Never oiled — dry when supplied and dry when refitted after a wash
- Direct replacement in the standard G 310 R airbox, no modification required
- Costs less than the standard woven element for the same housing
- Washable and reusable, with two years of warranty from the purchase date
Fine material, delivered slowly
Traffic produces a constant supply of very small particles, and a bike used in it draws air at low road speed for long stretches with no clean-air interval to dilute the load. Nothing about that looks dramatic on the filter face. It simply accumulates. A mat that filters through its depth has room to take that in without its restriction climbing as sharply as a surface-loaded element of the same rating, which is the practical argument for the PM189P14 on a machine that spends its life in town.
The price of the finer mat
It is still a trade. Against the 80-micron weave in the same box, this mat is rated at 1,800 l/m²/sec instead of 5,050, and the flow it gives up is given up on the open road as well as in traffic. Neither medium is better in general; each is drawn for different air. What neither of them does is make the bike faster — in an unmodified airbox this element leaves a standard G 310 R exactly as strong as it was. The benefit is a steadier intake restriction and a panel that is washed rather than replaced.
Care and cleaning
Clean the PM189P14 with compressed air on its clean face, worked outwards, and allow more time than a woven panel needs — depth-loaded material releases gradually. When air stops being enough, lukewarm water with a mild detergent finishes it; rinse until the water runs off clear. Dry in moving air at room temperature only, never with heat of any kind. Refit dry, with nothing sprayed on. Sprint Filter's maintenance sheet is in the Downloads tab.
