*Fitment. This premium quality universal oxygen sensor fits a variety of vehicles in both the pre- and post-catalyst positions. It is the front oxygen sensor for the following vehicles: 97-00 F-series 4.2 V6 (non California spec), 97-98 F-series 4.6L, 97-99 F-series 5.4L, 00 F-series 5.4L (Windsor module**, non-CA spec).

Essential for Performance. A malfunctioning oxygen sensor can cost you valuable HP and TQ, by relaying inaccurate readings to your truck's computer, which are used to calculate critical variables like air to fuel ratio, timing, and more. A failing sensor can cause your computer to retard your engine timing, inject the wrong amount of fuel - all costing you precious power and torque.

Direct Replacement. A failed or worn out sensor can drastically reduce performance, increase fuel consumption, or even cause you to fail emissions tests. These direct replacements from NTK, a market leader, ensure you'll be able to rely on these sensors for superior, consistent performance for many miles.

OEM Quality, Reliability. NTK is the world's leading supplier of oxygen sensors, and it's no wonder why. They individually test each sensor to ensure hassle-free performance, and they're built to the highest standard with premium materials. With waterproof, factory-fitted connectors, these oxygen sensors are the perfect direct replacement for your worn or failed OEM sensors.
