Redline Emissions Products® offers aftermarket OEM replacement sensors for both light and heavy-duty applications.

We carry a wide range of EGT, NOx, O2, and Pressure sensors. All of our sensors are OEM or better quality, to ensure performance and exact fit. Each REP Sensor with a threaded end comes with a tube of anti-seize to help prevent galling.

REP Sensors are backed by a  1-Year Warranty.


One of the things that set REP Sensors apart is their high level of quality. So, what does that mean?

Our extensive quality assurance process involves checking fit, function, and performance to allow our sellers the assurance they need that the part will work once installed. This also includes properly labeling and packaging each sensor (more on that later).

This provides peace of mind for resellers & distributors and reduces the chances of downtime because of a product failure due to defects.
