BBK Power Plus Series 62mm Throttle Body for 1991-2003 Jeep Cherokee, Comanche, and Wrangler (4.0L) - 1724

Fits 1991-2003 Jeep Cherokee, Comanche, Grand Cherokee, and Wrangler (4.0L).

The BBK Power Plus Series throttle body (MPN 1724) is engineered as a bolt-on replacement for the restrictive factory unit, specifically designed to increase airflow into your Jeep’s 4.0L inline-six engine. Featuring a larger 62mm bore, this performance upgrade provides up to 30% more airflow than the stock housing, resulting in improved throttle response and increased horsepower and torque across the RPM range. Because it is designed to work with the factory computer, no aftermarket tuning is required for installation.

Each throttle body is CNC machined from a high-quality 356 aluminum casting for a precision fit and long-term durability. To ensure smooth operation and a reliable seal, BBK utilizes double sealed bearings, O-ringed throttle shafts, and OEM-style die-stamped throttle linkages that accept your factory cables without modification. This unit is 50-state emissions legal (CARB approved) and manufactured in the USA.
