Q:Will this fit  Subaru Legacy GT 2.0 JDM?
Leroy
A:BEST ANSWERHi Leroy, I'm glad to help you out. We currently don't carry exhaust parts for the Legacy GT Japan models. But you can use the 21.26" wire length and 0.71" thread size for reference if it will match the original one you have on the vehicle. And if it matches, you can click on the link below for direct ordering to take advantage of our ongoing sale and limited stocks. I hope this helps and happy shopping. https://www.carparts.com/oxygen-sensor/denso/np2344732?can=CPAE1047 Show less
