Key Features

• Larger bore than stock throttle bodies for increased airflow.
• Includes idle adjustment screws for fine-tuning engine idle speed.
• Constructed from high-quality cast aluminum for durability.
• Designed to improve horsepower gains (typically 12-15 WHP).
• Comes with pre-installed TPS and MAP sensors for convenience.

Setup and Installation

Installation should be performed by a qualified technician. Always ensure the engine is cool and the battery is disconnected before beginning work. Refer to your vehicle's service manual for specific torque specifications and safety procedures.

1. Remove Air Intake: Carefully disconnect and remove the existing air intake system from the throttle body.
2. Disconnect Sensors: Unplug the electrical connectors from the existing MAP and TPS sensors. Ensure not to mix up the plugs.
3. Disconnect Hoses: Disconnect any emissions hoses connected to the throttle body.
4. Disconnect Coolant Bypass Hoses: If applicable, disconnect the coolant bypass hoses from the throttle body.
5. Disconnect Throttle Cable: Detach the throttle cable from the throttle body pulley.
6. Remove Hardware: Remove the mounting hardware securing the old throttle body to the intake manifold.
7. Remove Old Throttle Body: Carefully remove the old throttle body and discard the factory gasket. Clean the bore of the intake manifold thoroughly to ensure a proper seal.
8. Install TPS & MAP Sensor: Install the new TPS and MAP sensors onto the new PQY throttle body using the provided hardware.
9. Install Throttle Body: Position the new throttle body with a new gasket onto the intake manifold. Secure it with the provided mounting hardware. Tighten bolts evenly and to manufacturer specifications.
10. Connect Coolant Bypass Hose: Reconnect the coolant bypass hose(s) to the new throttle body.
11. Connect TPS & MAP Sensor Plugs: Reconnect the electrical plugs to the new TPS and MAP sensors. Ensure they are securely connected.
12. Connect Cable & Hoses: Reconnect the throttle cable, emissions hoses, and the air intake system.
13. Final Checks: Double-check all connections, hoses, and wiring for security and proper routing. Reconnect the battery.

Operating Instructions

After installation, it is recommended to perform an ECU reset to allow the vehicle's computer to learn the new throttle body's characteristics. The throttle body features an idle adjustment screw for fine-tuning the engine's idle speed.

• Idle Adjustment: Locate the idle adjustment screw on the throttle body (refer to Figure 4). With the engine at operating temperature, turn the screw clockwise to increase idle speed or counter-clockwise to decrease it. Adjust gradually until the desired idle RPM is achieved according to your vehicle's specifications.
• Coolant Line Bypass: The throttle body includes a coolant line connection. This can be bypassed if desired, especially for non-FITV (Fast Idle Thermal Valve) equipped vehicles, to reduce intake air temperature. Consult a professional for this modification.

Maintenance

Regular maintenance ensures optimal performance and longevity of your throttle body kit.

• Cleaning: Periodically inspect the throttle body bore and butterfly valve for carbon buildup. Use a throttle body cleaner (safe for coated throttle bodies) and a soft cloth to clean any deposits. Do not use harsh abrasives or solvents.
• Sensor Inspection: Check the TPS and MAP sensor connections for corrosion or looseness. Ensure wiring harnesses are intact and not frayed.
• Gasket Integrity: Inspect the throttle body gasket for any signs of wear, cracking, or leaks. Replace if necessary to prevent vacuum leaks.
• Throttle Cable Lubrication: If applicable, ensure the throttle cable operates smoothly and is free of kinks. Lubricate as needed.

Troubleshooting

If you encounter issues after installation, consider the following common troubleshooting steps:

If problems persist, it is recommended to consult a professional automotive technician.
