If you're thinking about upgrading your 2018-2021 GT Mustang to long tube headers, than you'll definitely need a few specialty mods to make it all possible and still keep your new pony street legal. Go ahead and order this brand-new Ford Front Driver Side Oxygen Sensor (JR3Z-9F472-A) from CJ Pony Parts now!

O2 sensors are an absolute must to measure the amount of oxygen in your pony's exhaust and deliver that information to your pony's computer. Your Mustang will automatically adjust air-to-fuel ratios to keep your 5.0L engine running efficiently and performing smoothing, so having a faulty oxygen sensor is a major problem. To keep your Mustang street legal and able to pass inspections, you'll need to have a fully-functional oxygen sensor no matter what. If you've noticed your engine light is on, a sudden decrease in MPG or a rough engine idle, than your O2 sensor may be malfunctioning and it may be necessary to replace that original sensor. If you're installing larger long tube headers on your pony, than you'll also need to pick-up this front left hand O2 sensor. This brand-new factory oxygen sensor is a direct-fit replacement to your pony's original, so what are you waiting for? Grab your new oxygen sensor now from CJ's!

*This oxygen sensor is sold individually.

Tech Tip: This Ford Front Driver Side Oxygen Sensor is a great part to pick up when installing Long Tube Headers on a 2018-2021 GT Mustang. Because of its longer length, you can easily use this as a substitution for the shorter OE passenger side oxygen sensor during installation.

Like most Ford vehicles, they all consist of thousands of different parts. Throughout every generation of each model, the Ford Motor Company has made many of their OE parts internally, meaning if you're looking to replace a specific part on your Ford vehicle, there's no better source than the OEM parts from Ford. CJ Pony Parts offers hundreds of parts from Ford, not only for Mustangs, but several other Ford vehicles in their lineup, so you should have no problem finding exactly what you need. Browse around and place your order now with CJ's!
