Jeep Wrangler V6 3.8 Liter Engine Gets More HP with K&N Air Intake System

 
 
The Wrangler has been Jeep's signature for more than 50 years. In 2007 Jeep purists were happy to see Wrangler's return to Jeep's traditional round headlights.

To get a performance increase K&N replaced the Wrangler's original intake assembly, including the air box, air filter and intake tube with an all new air intake design. The new system draws air through K&N a High-Flow Lifetime Replacement Air Filter (RU-4730) which increases airflow and filtering capacity.

A powder coated steel heat shield replaces the stock airbox and protects the K&N Air Filter by isolating it from engine heat. As air passes through the filter, it travels though a longer intake tube which uses a silicone hose that is mounted to the throttle body.

The heat shield bolts into the factory airbox location. The tube is supported by a bracket which is mounted onto the engine. Remove the factory air temperature sensor from the stock intake track then install it into the new K&N Air intake kit.

The 77-1553KP can easily be installed in 90 minutes or less and are backed by the K&N Million Mile Limited Warranty.
