K&N Motorcycle Air Filter PL-1720 — High-Flow Washable Cotton Gauze, OEM Fit

Built from multiple layers of oiled cotton gauze with a durable sealing design, this K&N performance air filter replaces the factory element with a reusable alternative crafted to match OEM fitment. It’s intended for riders who want improved throttle response and longer filter life without frequent replacements. The PL-1720 is manufactured to fit specific Indian models from 2020 through 2026, offering a straightforward swap-in installation for most applications.

How will this air filter affect my motorcycle’s throttle response and acceleration?

By reducing intake restriction, the PL-1720 permits more air to reach the engine, which can sharpen throttle feel and responsiveness. While results vary by bike and tuning, many riders notice crisper acceleration without needing immediate fuel system changes.

• High-flow cotton gauze media increases air volume to the intake.
• Oiled filter surface helps provide consistent airflow under load.
• Precision fit preserves intake sealing to maintain performance gains.

Does the K&N PL-1720 protect the engine as well as a disposable paper filter?

Yes — the PL-1720 uses layered cotton gauze treated to capture dust and contaminants while allowing higher airflow than standard paper elements. Proper installation and routine maintenance are key to ensuring ongoing engine protection comparable to factory filters.

• Multiple gauze layers trap fine particles without severely restricting flow.
• Special tack agent on fibers improves contaminant retention.
• OEM-style sealing beads prevent unfiltered air bypass around the filter.

What maintenance does a washable K&N filter require and how often?

The PL-1720 is designed to be removed, cleaned, re-oiled, and reinstalled rather than discarded. Cleaning intervals depend on riding environment: inspect more often in dusty conditions and follow the included service procedure for consistent results.

• Remove and visually inspect at scheduled service intervals or after dusty rides.
• Clean using a K&N-approved cleaner, rinse, allow to dry, then apply filter oil evenly.
• Reinstall ensuring the sealing bead seats correctly to maintain protection.

Will I need to change my bike’s fuel management after installing this filter?

Most riders do not require immediate fuel-management changes after fitting the PL-1720, but outcomes depend on the motorcycle and any other modifications. If you have additional intake or exhaust changes, a tune may be beneficial to optimize air/fuel balance.

• Typical stock setups remain compatible without remapping.
• Combined performance mods may change fueling needs—monitor spark and power delivery.
• Consult a tuner if you observe hesitations, lean conditions, or check-engine alerts.

Who is this for: The K&N PL-1720 is suited to touring and cruiser riders who own compatible 2020–2026 Indian models and want a durable, reusable air element that can improve intake flow and reduce ongoing filter purchases. It’s a practical upgrade for people who perform routine maintenance themselves or who prefer a higher-flow, long-life filter that fits precisely in place of the stock unit.
