• USDM Compatibility: Because this is an authentic JDM import, you must transfer all original USDM sensors, wiring harness, and specific brackets from your old engine to ensure 100% ECU compatibility and avoid error codes. • Maintenance: We highly recommend replacing all external gaskets (valve cover, oil pan), spark plugs, and the water pump prior to installation for long-term reliability. • Professional Install: Professional installation by a certified technician is required to validate the warranty. |
