ROUGH COUNTRY Cold Air Intake Kit 3.8L | Jeep Wrangler JK

The Rough Country Cold Air Intake Kit is the perfect upgrade for your Jeep Wrangler JK 3.8L (2007-2011). It replaces the restrictive factory airbox with an optimized system that draws cooler, denser air, improving throttle response, horsepower and engine efficiency.

• High-flow filter, reusable and washable for long service life.
• Large-diameter intake tube designed to maximize airflow.
• Noticeable improvement in acceleration and sound of the 3.8L V6.
• Works with the OE airbox for a clean installation.
• All hardware included: clamps, couplers and brackets.

Plug-and-play installation in your garage with basic tools, in under an hour. Ideal for those looking to wake up their JK's engine without complications and without touching the ECU. You'll feel the difference from the first start: better mid-range pull, a more aggressive intake sound and that feeling your Wrangler is finally breathing properly.

Rough Country quality, warranty and technical support from JKing4x4.
