When using the SCP/Kooks headers the collectors where the oxygen sensors are located is moved substantially rearward. You will have to use either our new long lead oxygen sensors or some O2 sensor extensions.
To help you choose which will work best for you, consider these thoughts. If you have more than 60K miles on your existing O2s, then buy our new O2 sensors because these sensors do degrade with mileage. If you have had engine coolant pass over your O2 sensors, then buy our new O2 sensors. If neither of these situations apply to you then go with our O2 extensions.
Available in either the 3-wire or 4-wire to suite your car. Just let us know what year car you have and that will tell us which you need.
BUY TWO sensors for all V-engine configurations.
