11-14 Grand Cherokee 5.7L Air Filter

The K&N Engineering 11-14 Grand Cherokee 5.7L Air Filter (SKU KNE57-1563) is engineered for Jeep owners who demand maximum engine efficiency without sacrificing air quality. If you've invested in a 5.7-liter Hemi engine, you understand that factory air filters restrict airflow and reduce both responsiveness and fuel economy. This performance-grade replacement restores your engine's breathing capacity, delivering measurable gains in throttle response and power delivery—critical upgrades for anyone serious about their Grand Cherokee's potential.

K&N's proprietary cotton-blend media and layered construction allow significantly more air volume to reach your intake while trapping fine particulates with precision. Unlike disposable paper filters that clog progressively and choke airflow, this reusable design maintains consistent filtration efficiency across thousands of miles—meaning your 5.7L maintains peak induction pressure longer. The washable media also cuts long-term ownership costs substantially; you'll clean and reinstall rather than replace repeatedly. The filter's engineered fit (14.25 x 12.25 x 22.125 inches) integrates seamlessly into the stock air box of 2011–2014 Grand Cherokee models, requiring zero modifications or bracket fabrication.

This upgrade suits any 5.7L Grand Cherokee owner—from daily drivers seeking fuel-efficiency improvements to weekend warriors optimizing for towing and off-road performance. Mechanically, the filter pairs flawlessly with stock intake manifolds and ECU calibration, making installation a straightforward 15-minute job requiring only basic tools. No tuning or reprogram needed; gains are immediate and noticeable on acceleration. For those planning future bolt-on upgrades (exhaust, headers, or intake manifolds), a K&N filter removes a critical airflow bottleneck and ensures downstream modifications perform at full potential.
