hello everybody. im new to this forum. i own a 03 focus 2.0 ghia and have just purchased a milltek manifold and system however wen i come to fit everything i realised i had not done my homework. the standard manifold has 2 lambda sensors and the milltek only has 1 and the hole is too far for the sensor to reach, what do i need to make it fit? also do i need a different flexi pipe as i wasnt supplied 1 with the system. any help would be appreciated. thanks, rich.

 

You need something with 2 Oxygen sensors, otherwise the engine ecu cannot function correctly, will lit the MIL and possibly limit the power and rpm range. Also you would get problems with the MOT.

 

I would get some bosses machined up or bought and welded into the exhaust and block the one up you have got ....or extend the wiring for that one and just weld one boss in.

 

i purchased the manifold from pumaspeed, i was presuming it would of been the correct fitment but im not sure why they dint make 2 lambda holes. is there any special type of wiring needed to extend the lower lambda? and whats need to block the other lambda?
