We tried calling NGK direct, but wire lengths are not part of their specs and their parts reps couldn't tell me what set we'd need.
I just did this swap. The JDM 2.0 had the coil mounted to the center of the intake and the wires were all the same length. I used the 2.5 intake which has the coil towards the back and off to the side. The spark plug wires were different lengths. This suggests to me that the previous owner likely used the 2.5 intake setup and the wires you order should be for the 2.5 not the 2.0.
