62mm Thottle Body - 05-06 Jeep 4.0L

The BBK Performance 62mm Throttle Body for 2005–2006 Jeep 4.0L engines is a bolt-on intake upgrade designed to increase airflow to the engine's combustion chamber. This single-blade, aluminum throttle body replaces the factory restriction and flows significantly more volume than stock units, enabling the engine management system to deliver fuel more efficiently across the throttle range. The 62mm bore diameter is a direct mechanical improvement that translates to measurable gains in mid-range and upper-RPM responsiveness.

Manufactured from aluminum and finished in natural (unpainted) form, this throttle body uses a stock-style flange that maintains compatibility with factory intake manifold mounting and vacuum lines. The single-blade design provides consistent, predictable throttle modulation without the complexity of electronic or multi-stage units. Installation requires no fuel system modifications or engine tuning—the ECU adjusts fuel delivery automatically through existing O2 sensors. The lightweight construction and precision casting reduce overall intake weight while maintaining the structural integrity needed for reliable operation across varying engine loads and ambient temperatures.

This upgrade targets Jeep Wrangler TJ and Cherokee owners running the 4.0L inline-six engine who seek improved throttle response without extensive engine modification. The 62mm diameter provides a meaningful step above factory flow capacity while remaining compatible with standard air intake systems. Off-road enthusiasts, trail drivers, and owners looking for more responsive power delivery at part throttle benefit from the mechanical simplicity and bolt-on installation. The natural aluminum finish withstands engine bay heat and allows for custom finishing if desired.
