The K&N 50-1542 is a NextGen cold air intake for 2011–2023 Dodge Charger V8 models with the 5.7L and 6.1L HEMI. Its semi-enclosed hybrid airbox helps lower air temperatures, uses an enlarged fresh air inlet for improved airflow, and offers better protection against contaminants. The tube is a black, cross-linked polyethylene part, and the manufacturer rates the system at a 16.7 CFM gain.
The case for paying more than a stock box rests on the manufacturer's dyno figures, which are estimated horsepower gains of 23.5 HP at 4905 RPM and estimated torque gains of 18.39 lb-ft at 1999 RPM, measured on the stock tune. The filter is a washable, reusable oiled cotton element that is paired with a washable, reusable High-Flow LIFETIME Air Filter featuring oiled cotton filter media. Owners searching for a 5.7 HEMI Charger cold air intake that drops ongoing paper filter costs will find that the reusable element matters more than the sticker price suggests.
Per the manufacturer, the High-Flow LIFETIME filter is washable and reusable, so it does not need replacing on a regular schedule. Confirm the current oil and cleaning instructions with the manufacturer before servicing it.
The manufacturer describes the gains as dyno-proven on the engine's stock tune, and lists the horsepower and torque numbers as estimates. Actual results will depend on the vehicle and conditions.
The manufacturer lists the kit as engineered for the Dodge Charger V8 5.7L, and the 2011–2023 range is part of the product title. Fitment details by submodel differ across sources, so confirm your specific trim and engine with the manufacturer before ordering.
The manufacturer states that the typical installation takes around an hour. Most owners with basic hand tools can handle it, but budget extra time for the mass airflow sensor. K&N's general install guidance for its cold air kits calls for disconnecting the negative battery cable, unplugging the MAF connector, and detaching the EVAP and crankcase vent lines from the intake plenum and valve cover before removing the stock tube. The MAF then moves onto the K&N adapter, which uses the provided gasket. Reconnect the vent lines to the new tube before you finish. Tighten all clamps, since a loose coupling at the throttle body is the most common cause of a vacuum leak.
