Bosch LSU4.9 258017025 vs 1928404687 wideband

[Elpizer2]

Hi guys

Is the 258017025 the same as 1928404687, I mean for a 4.9 LSU wideband that fits AEM gauge? My wideband sensor is bad, I am wondering if this one fits my AEM gauge, I have the old AEM gauge that does wideband simulation, it was working with a 1928404687

As long as it's a Bosch and the plug (D shaped) is the same it should be the same. I've contacted Innovate about this a few years ago and they confirmed as well.

Both part number show up in this datasheet. And also in the ebay link, it shows that they are interchangeable part numbers.

Both af these are Bosch 4.9LSU sensors. The difference being the length of the connecting harness. We use them on DSM's and on our Domestic Holley Sniper and Super Sniper units, as they are much cheaper than a Holley unit. The 17212 has a 14" lead and the 17025 has a 33" lead.
I DO NOT buy them on Ebay, I go to the auto parts store and get a truely genuine Bosch sensor.
