you said that the st165 plug wires are shorter, though you still used it for your st185 motor that required a longer stem? :shrug: .. i mistakenly bought the a set of st165 wires for my st165 which has a 2nd gen 3sgte. the wires were too short and would not reach the spark plugs.5speedGT4":3miycneg said:plug wires really are not, the st165 plug wires are slightly shorter than the 185s on the spark plug side, so the 185s will stick out on a 165.... but they'll work if you must, i had 165 plug wires on my 185 motor for a week or two until my trd wires came in.
