What does JDM stand for?

Japanese Domestic Market. JDM engines are usually "hotter" than their American counterparts. Most will not pass emissions in the state of California, so they are detuned upon import.

Generally it is the acronymn for Japanese Domestic Market products. JDM Honda or Toyota automotive parts are components imported from Japan.Often, JDM specialty parts and accessories for Japanes brand models may be for racing or special tuner applications.
