Sprint Filter P14 Air Filter for Dusty Conditions – Kawasaki Ninja 1100 SX (2025–2026) PM111P14

The airbox did not grow when the engine did. One element, PM111P14, is catalogued for the 1,000 cc sport-tourer and for the 1,100 that followed it: a larger engine draws more air per revolution through an opening that was not enlarged to match, so every restriction in the intake path counts for a little more here than it did before. The Sprint Filter P14 is a restriction by design. It filters to 14 microns and passes 1,800 l/m²/sec, against 80 microns and 5,050 l/m²/sec for the standard P08 medium. On a Kawasaki Ninja 1100 SX that is a real trade, and it deserves to be understood before the part is bought rather than afterwards.

Key Features

• A dry non-woven weave rated at 14 microns; flow 1,800 l/m²/sec
• The surface doing the filtering is roughly double that of other performance filters
• No oil in it, so nothing migrates onto the sensors this engine relies on
• It replaces the original element in the standard airbox — no modification, no remap
• Washing replaces buying: compressed air from the clean side, then refit
• Warranty two years; the element is designed to last the life of the motorcycle

What the extra displacement does to the trade

The 1,100 asks for more air at every point in the rev range than the 1,000 did, so the margin between what the intake can deliver and what the engine wants is slightly narrower. At the flow rates a road rider actually uses — part throttle, steady load, long distances — that narrowing is of no practical concern, and the large filtering area of this element absorbs it comfortably. Wide open near the limiter, or on a machine taken to track days, it is not nothing. For a bike ridden that way the standard P08 is the medium that suits the engine better.

Why a touring rider chooses it anyway

Because the question being answered is the other one: not what gets through the filter, but what gets past it. Long days in traffic feed the intake a steady diet of brake and tyre particulate; hot, dry summer roads add fine mineral dust that hangs at exactly the height the intake draws from. A 14-micron medium holds back a great deal more of that than an 80-micron one, and it does so with a dry fabric that has never seen oil, so nothing can be carried downstream onto the sensors this engine relies on. The element is washed rather than replaced, which means the intake resistance returns to where it started at every service instead of drifting upwards.

Care and cleaning

Work from the clean side outwards with compressed air, and put the element back dry. A deeper clean means lukewarm water with a mild detergent, rinsing until the water runs clear and then drying fully in open air, with no heat and no flame anywhere in that. Nothing is oiled before the wash or after it. The maintenance sheet is filed in the Downloads tab.

Fitment & Compatibility

Made for the Kawasaki Ninja 1100 SX, 2025 to 2026. The same PM111P14 element covers five machines built around this airbox, from the Ninja 1000 SX to the Z1100 and the Bimota KB4 pair; the complete list is in the Fitment tab.
