L2H2 WBO2---- NTK 24300; Bosch 13246/13025
 

Tried using this with my Hydra 2.7 upgrade...didn't seem compatible. Will work for other WBO2 applications or on a 92-95 Civic VX. I know this sensor works on 2.17 and 2.5 though. Was in the car for about 1 minute with car running.....so it's pretty much brand new. Comes attached to old harness used for the WB on the Hydra.

$150 shipped.
