How do I maintain a JDM car in the US?

Stock up on consumables (filters, belts, gaskets) during import — many JDM-specific parts have long lead times from Japan. Join model-specific forums for parts sourcing. Learn basic maintenance yourself — many US shops are unfamiliar with JDM-specific systems. Websites like RHDJapan, Nengun, and Amayama ship OEM parts worldwide. Budget 20-30% more for maintenance than equivalent US-market cars.
