K&N Cold Air Intake 2011-2014 Chrysler 300 / Dodge Challenger & Charger 6.4L V8

The K&N 57-1565 FIPK performance intake system is designed to increase horsepower and torque for your 2011-2014 Chrysler 300 / Dodge Challenger & Charger 6.4L V8, by providing your 392ci Hemi with a steady supply of cold air. To do this, the restrictive factory air box is replaced by an oversized K&N performance air filter, which is protected from hot engine bay air by a special heat shield that seals against the underside of the hood. The K&N air filter is made from an oil-treated cotton gauze material that can stop dirt particles that are the diameter of a human hair. The red oil then soaks into the dirt, causing it to actually catch and hold other dirt even when the filter gets dirty (depending on road conditions, it can go up to 100,000 miles before it needs to be cleaned).

Once the cold air coming up from below the motor gets cleaned, it's sent to the engine by a large-diameter K&N intake tube, which has been roto-molded to provide an unobstructed airflow path. It also has integrated fittings for the factory air temperature sensor and crank case vent hose, which preserves the factory emission system settings. This plug-and-play design requires no underhood modifications, and the entire system can usually be installed in about 90 minutes.

Once the K&N 57-1565 performance intake kit was fully developed, K&N installed it on a stock 2011 Dodge Challenger SRT8. Dyno testing showed 416.11 horsepower and 435.69 lb-ft of torque at the rear wheels, which equaled an estimated increase of 21.95 horsepower and 17.53 lb-ft of torque.

Estimated Horsepower 21.95 HP @ 5216 RPM
