hi guys,
after replacing the imrc on my 170 the second one has now packed up,
I am sick of it ....
I am looking at cat cams and their Vernier pulleys,
can anyone tell me what happens to the imrc box after the cams are installed and the actual inlet manifold itself ?
will it be opened and altered (the inlet manifold) and will the imrc control box still be plugged in or will it be mapped out and removed ?

thanks in avance !!
