  19. Difference between igniters

    I am looking to replace an igniter in my 96 JDM Supra SZ-R. The part number shown on the igniter right now is 89621-26010. Yet much of the information I find seems to suggest that 89621-33010 is the correct part number. Is 26010 required for JDM? or should I get the 33010?
