Installation & Notes

• Component Swap: To ensure 100% compatibility with North American (USDM) emissions and ECUs, you must transfer your original intake manifold, wiring harness, and all sensors from your original engine.

• Maintenance: Since this engine is timing chain driven, there is no belt to change. We recommend a fresh oil change (0W-20 Synthetic), new spark plugs, and a new thermostat before installation.
