• Confirm your vehicle’s engine size and current throttle body part number first.
• Expect a standard gasket and torque sequence—use factory torque specs.
• Clear stored error codes and perform throttle body relearn as recommended.
• If unsure, have a technician confirm fitment or install to avoid ECU faults.
