4-1 ashley manifold

[crazynovagsi]

Hi going to be fitting in my 4-1 manifold in soon and was wondering on the 1.4 sri originaly it has a lambda sensor in the manifold. Would i need 2 drill n make a hole for the lambda sensor to go into the 4-1 or can i leave it unplugged?

thanks

Yeah you will need it.
Best putting it down in the collector, by the sump.
But because its so far away from the cylinder head you will need a heated sensor.

what difference does it make? also i got a straight pipe with no cat.

Exactly what i did for mine. Bought a weld in boos. Just used the original sensor, but lengthened the wire. Ran fine for me.
