The K&N 33-2491 is a reusable, high-flow panel air filter made for the 2013–2016 Dodge Dart with the 1.4L and 2.0L L4 engines. K&N's own product page describes it as designed for high airflow while maintaining the filtration needed for long engine life. Its layered, oiled cotton-gauze media is washed and re-oiled rather than thrown away, and it arrives pre-oiled, so it is ready to drop in.
Compared with the factory paper element, which gets replaced on a recurring basis, this K&N element is built to be cleaned and reinstalled over the life of the car. That makes it a better value than a cheaper disposable paper drop-in once you count repeat purchases. For a 1.4L or 2.0L Dart owner searching for a K&N 33-2491 Dodge Dart 1.4L air filter, a reusable cotton panel filter for the 2.0L Dart, or a drop-in performance air filter for a 2013 to 2016 Dart, this is the part the manufacturer lists for that application. The swap is intended to be a simple drop-in replacement for the stock element inside the factory air box.
The manufacturer lists the 2013–2016 Dodge Dart with the L4 1.4L/2.0L fuel-injected engines. Some third-party fitment tables also show 2.4L-equipped Darts, which do not match that engine listing, so confirm your engine and model year with the manufacturer before ordering.
The manufacturer states that K&N filters of this type are pre-oiled and ready to drop into the factory air box, so no separate oiling step is described for this part.
The manufacturer describes this filter as an easy drop-in upgrade for the factory air box, and no intake modification is described on its product page.
This is a beginner-friendly swap. Loosen or release the air box lid fasteners, lift the lid, and remove the factory element carefully so as little dirt as possible falls into the intake. Wipe out the housing and clean the sealing surface, then seat the K&N element so it sits flat against the air box. K&N's general installation sheets for its panel filters warn that a poorly seated element can prevent a proper seal, and that closing the lid can take slightly more pressure than with a foam-sealed stock element. If the lid is bending or the pressure seems excessive, stop and recheck the seating. Lid clips and screws can also fall out during service, so keep track of them. The manufacturer's sheet specific to 33-2491 was not located, so follow the general guidance and check the lid seats fully before closing the clips.
