NGK o2 sensor

[Sy769]

Anybody have any comments on this one, part #21003

Better choice than stock?

Sparkplugs.com has it for $55.00 Anyone know of cheaper source?

Is this the 5 wire? TIA!

This is the three wire for the stock SyTy ecm.

If you are referring to the 5 wire used in the DIY wideband, they have that one also in NGK part #24169 It is $90


Are you building a DIY Wideband?

I was going to try that one or a Honda one with a Halmeter A/F meter to see how accurate it (the combo) was. A friend has an extra bung in his DP that it would fit in perfectly, and I'm gonna read it against the WB O2 A/F ratio on the dyno.
