This new filter was developed at K&N's United Kingdom facility. The Frontier is a popular vehicle in the UK. Nissan added more high-tech features to the Frontier that will assist off-roaders in extreme conditions. Hill Descent Control (HDC) makes it easy to go downhill without constantly hitting the brakes. Hill Start Assist (HAS) allows the driver to stop up-slope, release the brake pedal and not roll back for up to two seconds as the driver shifts a foot to the gas pedal.
K&N Diesel air filters capture airborne dirt particles while allowing a high volume air flow. These particles then cling to the outside of the filter and become part of the filtering media. Better dirt retention, better airflow and extended service intervals are all benefits of using a K&N filter.
