Replacement Air Filter-H ARLEY DAVIDSON TWIN CAM

The K&N Engineering Replacement Air Filter for Harley Davidson Twin Cam engines represents a proven upgrade over restrictive OEM paper elements. As a seasoned mechanic, you know that air intake quality directly impacts combustion efficiency, throttle response, and engine longevity—especially on air-cooled V-twins where heat management is critical. This replacement air filter is engineered specifically for Twin Cam powerplants found in Dyna Wide Glide and other modern Harley platforms, delivering measurable gains in airflow while maintaining proper filtration.

Built from reusable cotton media and engineered by K&N's proven design, this filter element operates on a different principle than disposable paper—the pleated cotton construction traps contaminants on the outer layers while allowing maximum air passage through the center. The red cotton media is treated with K&N's signature tacky coating, creating a semi-permanent barrier that can be cleaned and re-oiled (using K&N cleaner and oil kits) for thousands of miles of use. At 7.063 x 4.750 inches with a 1.625-inch tall profile, the dimensions are optimized to fit the stock Harley air box without modification, ensuring zero tuning or fuel mapping adjustments are needed.

Riders and builders upgrading 2008–2016 Dyna Wide Glide models benefit from the combination of increased airflow and reusability—you'll notice crisper throttle response and reduced heat soak compared to factory paper filters. Installation is straightforward; simply remove the old element and drop in the K&N unit, securing with the stock air box clamp. Over a bike's lifetime, the cost-per-mile of this reusable filter is substantially lower than serial OEM replacements, making it ideal for high-mileage riders and those committed to long-term performance maintenance on their Twin Cam motors.
