K&N Engine Air Filter HD-0910 for Harley-Davidson — Washable High-Flow, OEM Fit

The K&N HD-0910 is a washable, high-flow motorcycle air filter engineered to boost airflow and protect your Harley-Davidson’s engine while delivering a precise OEM-style fit.

Built from multiple layers of oiled cotton gauze and finished with durable sealing beads, this K&N performance filter replaces the factory element to increase airflow, sharpen throttle response, and enhance acceleration without needing routine replacement. It’s engineered to fit specific Harley-Davidson touring and Dyna models for a trouble-free installation and long-term service life. The HD-0910 combines durable construction and reusable filtration to lower maintenance cost over the life of your bike.

How does this filter affect power and throttle response?

By allowing more air into the intake while still capturing contaminants, the HD-0910 can help your engine breathe more freely. Riders typically notice crisper throttle action and improved roll-on acceleration when the fuel system is already tuned for increased airflow.

• High-flow cotton media increases airflow versus many paper elements
• Oiled gauze media traps dirt while permitting greater volume of air
• Compatible with many Harley-Davidson fuel systems without immediate remapping

Is the K&N HD-0910 reusable and how do I maintain it?

This K&N element is designed to be cleaned and re-oiled rather than discarded. Routine cleaning with K&N service products restores airflow and filtration performance; follow the included care instructions for best results.

• Wash with a K&N-approved cleaner to remove trapped particulates
• Re-oil the filter lightly with K&N filter oil after it dries
• Inspect sealing surfaces and gasket before reinstalling

Will it fit my Harley-Davidson model and install easily?

The HD-0910 is manufactured to match factory dimensions and sealing contours for specific Harley models, so it installs using the stock airbox without modification. Confirm compatibility against your model year before purchase to ensure a direct fit.

• Precision sealing beads and custom seals for OEM-style fit
• Application-specific design for select Harley Touring and Dyna bikes
• Drop-in replacement for the listed vehicle applications

What protection does it offer against dirt and contaminants?

Layers of oiled cotton gauze and a tack-enhanced surface capture and hold particulates while allowing higher airflow than many standard paper filters. The construction balances engine protection with performance, helping prevent abrasive debris from entering the intake.

• Multiple cotton-gauze layers filter incoming air effectively
• Special tack treatment helps retain trapped dirt
• Durable frame and sealing materials resist degradation over time

Who is this for: The K&N HD-0910 suits riders who own compatible 2009–2017 Harley-Davidson Touring and Dyna models and want a long-lasting, serviceable air filter that prioritizes airflow and engine protection. Choose this filter if you value improved throttle response and reduced ongoing replacement costs, or if you maintain and tune your motorcycle and prefer performance-focused, reusable components. Always verify fitment for your exact year and model before ordering.
