I went to one of the local salvage yards this weekend for 40% off weekend. I found an '04 Matrix there that still had the throttle body and intake. I pulled them off as one unit. I am going to have George at maxbore enlarge both of them. Unfortunately, he will be on vacation for the next two weeks and I have to wait. I have a couple of questions. First, do I separate the two before shipping up to him? Second, did anyone who had both items bored out see marked increase in power and/or mileage? (I had the throttle body bored out on my Dakota and noticed a quicker throttle response and small amount of power but the mileage stayed the same.)
Just curious.
