O2 sensor

Post by head2wind »

Has anyone replaced their O2 sensor with a Bosch 15733 (universal 4 wire)? the OE replacement O2 PN is 13255, which is between &75-110 depending on where you look. The 15733 is all over the place and can be had for $50 or less.

Anyone have some thoughts or insight?

i replaced mine with This (bottom of the page P/N #USOS-4000) 4 wire and its worked great. I needed to extend the wires anyways (bellmouth DP) so no connector made it easier, i just cut the old one off and soldered it to the new one. Then ran an extra wire for the sensor ground to the tranny grond point.
