K&N 63 Series Cold Air Intake for 2024+ Jeep Wrangler 4xE
⚠️ 4xE Hybrid Only: This intake is engineered specifically for the Jeep Wrangler 4xE plug-in hybrid (L4-2.0L). It will not fit non-hybrid Wrangler models.
Guaranteed Power Gains — No Tune Needed
K&N backs this intake with a guaranteed dyno-verified power increase of +19.24 horsepower and +25.47 lb-ft of torque for the Wrangler 4xE's 2.0L turbocharged hybrid engine. No ECU tune required — bolt it on and drive.
The 63 Series uses a high-density polyethylene (HDPE) rotationally-molded intake tube engineered to maximize airflow volume while maintaining a precise fit to factory engine bay dimensions. A custom heat shield isolates the intake from hot engine bay air — especially important on a turbocharged engine where intake temps affect performance.
The K&N High-Flow Air Filter uses oiled cotton filter media for superior filtration efficiency with unrestricted airflow. Unlike disposable paper filters, it's fully washable and reusable — clean it every 50,000–100,000 miles and it's good as new.
