This extension lead plugs directly into factory wiring to retain your o2 sensor when fitting a decat manifold. Tried and tested on my own track car I have taken special care to use good quality cable and heat sheilding to ensure there is no added resistance from using this extended lead which means lambda readings remain accurate - Essential for a healthy running engine. Fits GREEN PLUG Ford Puma and MK4/5/6 ST150 Fiesta. May fit other Ford vehicles but is designed to be used on the above vehicles with a decat manifold due to cable length. Please get in contact if you require a custom length cable.
