Mopar 04593858AB Throttle Body for 08-11 Jeep Wrangler JK

The throttle body on a fuel injected engine controls the amount of air being delivered to the cylinders for combustion. The Mopar Throttle Body is a factory replacement for the original unit that is starting to wear out. If the springs or flap are not performing properly you could be starving the engine of much needed air when you are accelerating and at the same time could be dumping too much air into the engine when you are at rest. These inconsistencies will lower your fuel economy and power output from the engine. Have a smoother running system with a new throttle body and make sure that the engine is getting the proper air to fuel mixture.
