Hi, it's compatible with any engine that uses NGK BPR6E-11 or equivalent as standard spark plug. Generally it means any car that uses spark plug with 14mm plug thread diameter, projected insulator, resistor, heat rating #6, 19mm thread reach, and 1.1mm plug gap. As for the plug gap of 1.1mm, I would say it's up to the ignition spark strength, it the engine has been modded with higher ignition power, U might want to increase the plug gap from standard to 1.1mm.

If your car is not using NGK spark plug as standard, you might want to refer to the spark plug cross reference for further detail on the compatibility.
