June 11, 2009: EDIT: Bummer, The $99 o2 sensors are no longer available, they now have NTK-NGK @ $190, so the deal is gone ;( .
In the end I located a replacement L1H1 for $99 shipped that performs perfectly. The sensor is visually identical to the l1h1 oem Honda that was on my VX and is stamped made in Japan with an internal resistor. I ordered it from AutopartsDirectToYou.com here:
http://stores.channeladvisor.com/Aut...t=5&scat=20363 and is Item 13208452 Honda Civic o2 Sensor
No CEL, plug and play, visually identical including internal resistor, jumped my mileage from 40.5 to near 45MPG and smoothed out the engine stumble at 1850RPM. I am freakin satisfied with this purchase.
fwiw, the sensor matches the readings posted in nowhhs post #11 above for the NTK brand.
