Air Intake for 2007 to 2011 Jeep Wrangler
To get a performance increase K&N
replaced the Wrangler's original intake assembly, including the air box, air

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