Actually in a newer Civic the NTK L1H1 wideband pump cell sensors is
used. For those who don't know, it's part of NGK. I do like NGK
products. Denso doesn't have this kind of technology. The better
designed Bosch LSU4 series is a highly regarded alternative for other
wideband applications. Just google.

Now I recognize people's preferences differ. But if the cheap denso
works, why not. But I say go with a Bosch PLANAR type sensor for
i.k.e.'s application.
