JDM Engine provides its customers with used imported Japanese engines with low mileage. External parts such as belts, hoses, seals, gaskets, and plastic covers might be damaged during shipping and can be replaced by the customer’s mechanic using parts from the designated vehicle. Cosmetic damage like scratches on valve covers does not affect performance. Replaceable parts such as sensors or air intake boxes may be missing if broken or damaged.
