– A high-quality air filter for a KTM Duke 125, like the DNA air filter, is designed to significantly increase airflow while maintaining high filtration efficiency.
– Specifically, DNA filters, with their 4-layer cotton design and embedded support frame, offer a 40.94% increase in airflow compared to the stock KTM foam filter.
– This increased airflow can lead to improved engine performance, including potentially increased horsepower and acceleration.
Key Features:
High Filtration Efficiency:
A good filter should maintain a high level of filtration to protect the engine from harmful particles. DNA filters, for example, are tested to 98-99% filtering efficiency (ISO 5011).
Increased Airflow:
A primary goal of a performance air filter is to allow more air into the engine, which can improve power output. DNA filters are designed for high-flow applications.
Washable and Reusable:
Many performance air filters, including those from DNA, are designed to be washable and reusable, offering long-term value.
Direct Replacement:
They are typically designed as a drop-in replacement for the stock air filter, making installation relatively straightforward.
Proper Fit and Function:
The filter should be designed to fit perfectly within the airbox and function as intended for the specific KTM Duke 125 model.
Fuel Recalibration:
In some cases, particularly with high-flow filters, a fuel recalibration of the engine may be necessary or recommended for optimal performance.
