The M1 intake showed back up from Wilson. As usual they did a super nice job on the porting. The port match appears to be perfect from what I can see and feel.
do they section it to work on it?
I don't think so but I do not know how they get the super nice finish all the way down the runners. The finish is very even everywhere. I don't have the motor skills to do anything close to this type of work.
