Jeep strives to manufacture vehicles that have no boundaries and based on that goal, more power could help remove any boundaries that still exist. Many manufacturers do not offer the estimated horsepower to the wheels, but rather test engine horsepower at the crankshaft. Vehicle drivetrain components suck up a lot of horsepower, often referred to as "drivetrain loss," leaving some owners wishing they had more power.
One way to make a few extra ponies to the wheels is to install a K&N cold air intake like part number 77-1563KP. Testing has shown K&N's 77-1563KP air intake can get an estimated extra 15 horsepower at 4500 RPM and an estimated 23 pound feet of torque at 3661 RPM to the wheels without any modifications to factory programming. This substantial horsepower increase is made by replacing the restrictive factory intake system with high-flow K&N components engineered to increase performance. The 77-1563KP air intake fits 2011 to 2015 Jeep Grand Cherokee and Dodge Durango models with 5.7 liter HEMI engines.
The 77-1563KP kit utilizes an aluminum intake tube with a durable polished finish, powered coated steel heat shield, and an oversized K&N high flow, washable and reusable air filter. The filter can go up to 100,000 miles under normal highway driving conditions before cleaning is required. When cleaning is due, the filter can be easily completed using K&N's 99-5000 or 99-5050 Recharger® Kit. These high quality components are very durable, easy to install and backed by K&N's Million Mile Limited Warranty.
