Question:

Would I need harness extender for an 08 g37 coupe? If so where would I find one? - Helen

Hi Helen, all vehicles will need their O2 sensor harnesses extended. ISR currently only makes plug and play harnesses for the earlier DE engines, so for anything else, you'll just need to manually extend the harnesses by adding wire.

Question:
