More Power for the Open Road for H-D Motorcycles with K&N Intakes
- 12 mrt. 2021
It all began with motorcycles back in 1969, when Ken Johnson and Norm McDonald created the original oiled High-Flow Air Filter™ for their off-road bikes. Since that time, K&N® has continued to develop cutting-edge performance products for motorcycles, and offers intake systems for dozens of Harley-Davidson motorcycle models and years including newer Fat Boy, Softail, Road Glide, Street Glide, Road King, and Electra Glide models.
For Harley-Davidson owners interested in a guaranteed increase in horsepower and torque, K&N® offers performance-enhancing air intake systems available in multiple styles and finishes—engineered to protect your engine from most harmful dust, dirt, and contaminants, and designed to provide benefits including a guaranteed increase in horsepower and torque, top-quality engine protection, and robust engine sounds. For many models and years, these new intakes are 50-state legal* (please view the individual product pages for details on CARB status for your vehicle model/year).
