speaking about 'fake' parts sold at auto supplies, actually they can recategorized the parts with -----taiwan/china, korea, or japan original, although exactly same looks yung mga parts made in the 3 different countries and all bear the label "Made in Japan".

Kaya when I buy parts for my car, specified ko talaga ng original japan made and kukunin ko. Pero take note na meron din mga japan made parts though hindi oem parts.
