The Bosch 17025 is a wideband oxygen sensor with a 0-5 V output, built for aftermarket engine management systems such as Holley Terminator X and Sniper, and for tuning gasoline, diesel or E85 engines. It reads air/fuel ratios from 10:1 to 20:1, activates in under 7 seconds and is rated to 1030°C. It uses an 18 mm threaded mount with a D-shaped connector and comes with OE connectors, a harness and anti-seize pre-coated on the threads. At $79.99 at Real Street Performance as of November 3, 2026, it sits at the low end of its recent range, with three stores pricing it new.
