Installation & Maintenance Notes

• Pre-Install Refresh: To ensure the longevity of this high-performance V8, we recommend a "pre-install refresh" including new genuine Lexus water pump, serpentine belt, spark plugs, and fresh synthetic 0W-20 or 5W-30 motor oil (consult your vehicle’s service manual for specific viscosity).

• Fuel Requirements: Due to the D-4S direct injection system, it is mandatory to use Top Tier 93+ octane premium fuel to prevent carbon buildup and ensure optimal performance.

• Professional Tip: When swapping, carefully inspect all electrical connectors and vacuum lines for dry rot. Transferring your USDM-spec intake plenum and specific emissions components is recommended to maintain exact compatibility with your vehicle’s factory OBD-II emissions readiness monitors.

• Cooling: The 1UR-FSE produces significant heat. Ensure your Lexus cooling system is thoroughly flushed and that the radiator/thermostat are in peak condition before startup.
