Googling those part numbers didn't result in anything conclusive. Tech support at NTK USA said that the correct replacement for an L1H1 is supposed to be an LZA09. The shipped to me is an LZA06. They have no data on LZA06’s since they are only sold in Japan but did say that there are big internal differences between each model (LZA06, LZA07, LZA08, etc.)

I almost bought this same one, but the seller didn't respond to my question regarding this being an authentic L1H1 sensor that the listing claims. Something seemed fishy.






I could care less how rough the engine is during lean/stiochiometric burn transition - might be a good thing as long as it hits the 1.55 target lambda and stays there.

My O2 is tired and is getting jerky under steady cruise, looking forward to seeing the results.

$400 will by a lot of fuel, but I have hope the solution works.
