So, one of the heat shields fell off on my 2000 Insight MT and severed my secondary 02 sensor wires on the way down. So the dealer tells me that this needs to be replaced. I have researched on this forum and also online and I have not found definitive evidence that there is an aftermarket [Bosch, etc] secondary O2 sensor that bolts up w/o modification and works as well as the OEM sensor from Honda. This part [36531-PCC-014] is around $267 at the least. I've found that Bosch 13075 is supposed to fit that year Insight but no evidence from anyone with an Insight that it actually fits or conforms to OE specs enough to justify not going with the Honda sensor on this. Has anyone had any experience with replacing this sensor that can shed some light on this for me?
