ThunderMax Replacement 18 mm Wide-Band O2 Sensor
$129.95
Fits: ThunderMax ECMs with AutoTune closed-loop control, including the Gen 3 WaveTune module and earlier AutoTune-equipped ThunderMax kits. ThunderMax part number 309-355 (Drag Specialties 1022-0039). The 18 mm wide-band oxygen sensor the ThunderMax AutoTune system reads to keep the air/fuel ratio on target. Sold each; a ThunderMax ECM runs one sensor per cylinder, so order two to replace both.
Direct replacement for the sensors supplied with the ThunderMax kit: screws into the 18 mm bung and plugs into the ThunderMax harness. A tired or contaminated sensor shows up as drifting AutoTune corrections, lean or rich running and a rough idle; a fresh sensor puts the closed-loop system back on accurate readings. Made in the U.S.A.
