I bought the wideband a couple months ago. Rugged (dropped it on concrete by mistake), reliable, responsive unit. Be sure to install it a couple feet from the turbo on turbocharged cars to ensure reasonable sensor life. I ran the wires under the center console and behind the radio, under the steering column and into the A-pillar. There was wire to spare. Great purchase which will let me identify any air fuel ratio issues which might crop us as I mod my MR2.
