2020-03-20 - Intake Manifold Modification

Q.
If one were to:
1. Modify a stock, cast aluminum intake manifold by cutting length out of runners, would this cost VPI points?
2. Modify a similar manifold by cutting open the stock intake plenum, adding material between the two halves, and welding back together. Material points?
Assume it is the OE manifold for the car you are using

A.
1. No points
2. Material points

Be cautious about building a copy of an intake that exists as it will add points.
With the "2" intake modification, you would be best served to submit your plans to tech for approval.
