Compatible with the 4.2 except for the plug if I'm reading it correctly. https://www.innovatemotorsports.com/xcart/bosch-lsu-4-9-o-sensor-p-n-3888.html Kevin

To make a long story short, it's better.... https://www.ecotrons.com/accurate_lambda_meter/bosch_lsu_49_is_superior_to_lsu_42_sensors/ Uses current instead of air, for reference.
