The K&N Air Filter replaces the factory air filter on all 6.2, 6.5 & 6.5TD H1. The K&N filter offers a greater surface area than paper filters (no metal mesh reducing airflow). This results in the K&N filter amplifying the engine induction acoustics, quickens throttle response and increases power.
If you don't remember the last time you replaced your air filter, it's probably time for some new ones. Replace your factory air filter with K&N unit. K&N air filters cost a fraction of the cost of the OEM air filter and never need to be replaced.
If your current filter has a nut built in, a 5/16-18 wing nut is required.
