Flynsu 62mm High-Flow Throttle Body for 1996–2001 Jeep 4.0L — Direct-Fit OE Replacement, Improved Throttle Response

Flynsu's 62mm high-flow throttle body is a direct-fit replacement for 1996–2001 Jeep Cherokee, Wrangler (TJ) and Grand Cherokee 4.0L engines, designed to restore throttle response and airflow to OE specifications.

If your 4.0L Jeep is showing sluggish throttle response, inconsistent idle, or check-engine codes tied to the throttle system, a worn or contaminated throttle body is a common culprit. This Flynsu unit is built to match OE fitment and mounting points (OE Part# 53032023AB), letting you swap the assembly without major modifications. The 62mm bore supports the engine's airflow demands while providing a durable alternative to an aging original part.

How does this throttle body affect drivability on my 4.0L Jeep?

Replacing a fouled or failing throttle body can noticeably improve throttle modulation and stabilize idle speed by restoring consistent airflow metering. The Flynsu 62mm design keeps airflow characteristics similar to the original while removing deposits and restoring a clean bore.

• 62mm bore size tuned for 4.0L Jeep airflow requirements
• Direct-fit mounting and electrical connector compatibility with OE harness
• Improves throttle response and reduces hesitation compared with a dirty unit

Will this part fit my Jeep Cherokee, Wrangler or Grand Cherokee?

This throttle body is a direct replacement for Jeep 4.0L models from the 1996–2001 model years, including Cherokee, Wrangler (TJ) and Grand Cherokee. It follows the original equipment part number and attachment points to make installation straightforward.

What should I expect during installation and tuning?

Installation is intended to be plug-and-play for vehicles that use the referenced OE part number; most swaps require only basic hand tools.

No permanent ECU remapping is required for stock engines.
