The K&N 63-1114 is a cold air intake for the 5.7L V8 in the Dodge Charger, Chrysler 300 and related Challenger applications. It replaces the factory filter and intake tube with a high-density polyethylene tube that is rotationally molded, paired with an oversized oiled cotton filter. The manufacturer says the kit reduces restriction for a guaranteed increase in horsepower and torque, and lists an estimated gain of 11.77 HP @ 4513 RPM and 14.5 lbft of torque. A stock setup restricts airflow in two places: a replacement performance air filter can only flow so much when its size is limited, and the air path from the filter to the throttle body can be restricted by the OEM intake tube. Owners on user forums commonly report an increase in throttle response and a deeper throaty sound, though some estimate smaller seat-of-the-pants gains than the published figures.
Fitment is the first thing to verify. The manufacturer lists this kit for DODGE CHARGER/CHRYSLER 300 V8-5.7L F/I, 11-23, while this listing's title names 2011–2013 Charger, Challenger and 300C models, so confirm your model year against your VIN before ordering. Once installed, the manufacturer says the filter only requires cleaning every 100,000 miles under normal highway driving conditions, which keeps long-term ownership simple. For buyers searching terms like 63-1114 cold air intake, 5.7 Hemi Aircharger, Charger 5.7 intake upgrade or RU-1042 replacement filter, this is a bolt-in upgrade that works with the factory engine management.
The manufacturer lists the application as the fuel-injected 5.7L V8 in Charger and 300 models from 2011 through 2023. The product title names 2011–2013 Charger, Challenger and 300C, so confirm your exact year and model against the manufacturer's fitment tool before ordering.
According to the manufacturer, the filter only needs cleaning about every 100,000 miles under normal highway driving. Harsher conditions such as dusty roads will call for more frequent service.
Older listings cite a 21.09 HP figure, but the manufacturer's current estimate is 11.77 HP. Owners on user forums have questioned the higher number and reported smaller gains, so treat any single dyno number with caution.
The manufacturer estimates installation at 60 minutes or less using simple hand tools, and the kit includes six stainless steel clamps and two couplers. Owners report that the instruction photos are hard to read on bracket orientation, so compare the brackets carefully against the diagrams before tightening anything. Check that the tube clears the engine bay and that every clamp and coupler is fully seated before starting the engine.
