Rubicon Express Throttle Body Upgrade Bolting In Throttle Body
We used the factory bolts to secure the new throttle-body assembly to the manifold.		 Rubicon Express Throttle Body Upgrade Iac Sensor Installation
The IAC sensor and housing were then transferred to the new throttle body using the provided Torx wrench. We used a set of Vise-Grips to hold the provided Torx wrench and create more leverage.		 Rubicon Express Throttle Body Upgrade Measuring Bore
With the new throttle body assembled and ready for installation, we used a set of digital calipers to verify its larger 62mm throttle bore. The factory throttle body has a 60mm bore.

The new RE throttle body is ready for installation.		 Rubicon Express Throttle Body Upgrade Cable Attached To Throttle Body
With the bolts securely tightened, each of the sensors was plugged into the appropriate wire lead. The throttle and transmission cables were also attached to their respective locations. The RE 62mm throttle body also offers a secondary position for throttle-cable attachment that is said to produce increased off-idle throttle resolution. It's also noted that use of this throttle position is designed for off-road use only. In effect, it simply opens the butterfly a bit faster to improve acceleration.

As a final step, the K&N air tube was installed. The initial testdrive proved to be very positive with noticeable horsepower improvement, especially in the 2,500-4,000 rpm range.
