I came across a P73 itr intake manifold for $80. i'm thinking of getting this to put on my EM1 but is it worth doing?

I did some research and unless its mildly built i'm going to loose low in hp and torque and see very minimal gains on the high end...

i am putting on comptech headers on today with a bolt on magnaflow high flow cat (since my oem went bad).

so its this a good buy or not?
