Sprint Filter P14 Air Filter for Dusty Conditions – CFMOTO NK 300 (2019–2020) PM227P14

A finer material catches more, and catching more is the same thing as loading sooner. That is the half of the trade which never appears on a specification sheet: alongside its 14 microns and its rated 1,800 l/m²/sec, a P14 asks to be serviced more often than the standard weave would in the same air. On a CFMOTO NK 300 that is a reasonable request rather than a drawback, but only because of what a service involves here — the element is cleaned and refitted, so a shorter interval is spent in time rather than in parts.

Key Features

• Dry non-woven medium at 14 microns, chosen where retention matters more than flow
• Rated 1,800 l/m²/sec, against 5,050 for the standard weave in the same housing
• Never oiled, at any point — there is no coating to apply, spread or wash back out
• Around double the filtering area of a typical performance element
• Fits the standard NK 300 airbox in place of the paper panel, without modification
• Compressed air is the whole service; two years of warranty from purchase

A shorter interval, not a shorter life

Restriction rises on any filter as it loads, and a fine medium reaches a given level of restriction sooner than a coarse one in the same conditions. With a disposable panel that has a real consequence, since every reset means another part. Here the curve is put back to where it started with a compressor, and the element comes through it unchanged: Sprint Filter designs the P14 for the working life of the motorcycle rather than to a replacement interval, and covers it for two years from purchase. The honest description of this medium is that it asks for attention more often and for a new part never.

Where the trade stops paying

If an NK 300 lives on clean, sealed roads through the year, the standard element in the same box is the better balance — it filters coarsely enough for that air and flows nearly three times as freely. The P14 belongs where the air earns it: gravel, farm country, long dry summers, construction traffic. Either way the same limit applies, and it is worth stating plainly: a drop-in filter does not make a standard NK 300 noticeably quicker. This is a decision about what gets into the engine, not about what comes out of it.

Care and cleaning

Because the service is what makes this medium workable, it is worth doing properly. Air from the clean side, moved slowly enough to reach the whole panel, is the standard treatment. Water is the fallback for oily residue: lukewarm, mild detergent, rinsed thoroughly. Dry in air alone and never with heat — a hot-air gun, a radiator or a flame will damage the material — and refit the PM227P14 only once it is dry throughout. Sprint Filter's maintenance sheet for it is in the Downloads tab.
