• Mounting type: direct mount; expect a straightforward OEM-style swap.
• Confirm original part number and inspect connectors for compatibility.

Will I need calibration or additional parts after installation?

Some vehicles may require a relearn procedure or diagnostic reset so the engine control module recognizes the new throttle body. Basic hardware like new mounting bolts or a throttle body gasket may be recommended if the originals are worn; sensors and wiring should be inspected for damage before reassembly.

• Perform an ECU relearn or use a scan tool if recommended by service manual.
• Inspect and replace the throttle body gasket and mounting bolts if needed.
