Sorry guys but I have many questions. I've done plugs a hunderd times on my American vehicles so this is a little different..Is the small flathead brass screw the only thing holding the coil in place? The opposite corner is a locater boss?? I assume the coil needs to be persuaded out by just pulling on it or turning it?? Is there a resistor end underneath the coils??? So I am correct in assuming that each wire is at least 2 pieces? Do you just pull the end off & push or screw the new resistor tip on?? I assume I will need to check for continuity w/ a Fluke or voltmeter to verify??Are the spark plugs supposed to be just 'snug' when re-installed or is there a torque rating that needs to be strictly adhered too? Thanks for being helpfull so far!
