Will I need to install Reducers With Oxygen Sensor, Emissions Code 3-Amber if I install on my 1984 Monte Carlo SS with 305 engine?JohnDoe157Sep 02, 2024
Best Answer:Hi Joseph, thanks for initiating contact. If your emission code is 3-Amber, yes, you will need reducers with oxygen sensors. This is only for off-road and racing use and will not fit angle plug heads.
