Sprint Filter P08 Air Filter for Road & Track – Royal Enfield Continental GT35 EFI (2015–2018) CM195S

Four model years, 2015 to 2018, and a 535 cm³ engine that no other machine on this part number shares: the Continental GT35 EFI is the short entry in the CM195S list. Short entries are usually where parts supply turns awkward. Here it does not, and the reason is visible in the fitment list itself — three other Royal Enfields carry the same element, two of them still being built, so the number stays current for reasons that have nothing to do with how many GT35s exist.

Key Features

• One layer of woven polyester, dry in use, with no oil to apply or renew
• Rated 80 µm filtration and 5,050 l/m²/sec of flow through clean cloth
• Approximately double the filtering area of other performance elements, in the untouched airbox
• Polyester threads from ø 22 micrometres — a thread dimension, not a pore size
• Exchanges directly for the factory panel: no modification, no remap, no fuelling work
• Washed instead of replaced, designed to outlast the service schedule, two years of warranty

Why the short entry does not matter

A discontinued machine usually inherits a discontinued parts list, and the owner starts stockpiling. This element is not in that category: it is specified against the airbox, and the airbox went on being fitted to motorcycles that are still on sale. What that buys a GT35 owner is not a discount but an ordinary situation — a filter you can order when you need one instead of one you keep on a shelf. And since this one is cleaned rather than consumed, the second order tends not to come at all.

The honest limit

None of this makes the motorcycle faster. A drop-in element does not give a standard machine a noticeable amount of power, and the largest engine on this number is still a mild single. What it does give is a resistance that stays low across the interval instead of climbing as a paper panel loads, and an intake with no oil anywhere upstream of the throttle body. For genuinely dusty use Sprint Filter offers the 14 µm P14 for this box at 1,800 l/m²/sec: finer, slower, and the right choice only where the air demands it.

Care and cleaning

Dry service, air from the clean side outwards, across the whole face of the CM195S until the cloth looks even again. Mild detergent in lukewarm water deals with anything greasy that air alone leaves behind, followed by a proper rinse. Drying happens in air at room temperature — heat, in any form, is what ruins these elements — and the panel returns to the box untreated. The maintenance sheet is filed in the Downloads tab.

Fitment & Compatibility

Fits the Royal Enfield Continental GT35 EFI, 2015 to 2018. The same number covers the Classic 500 from 2009 to 2020 and both 500 EFI Bullets — B5 and Trials — from 2011 to 2026: four machines in total on one element. Confirm the year of your own machine in the Fitment tab.
