Map Adapter by R2 Motorsports. Our dual port boost reference adapter allows you to extend the hole out further and gives you a 3/16″ vacuum port on both sides. Additionally, this still fits the OEM map sensor and keeps you from drilling into the supercharger lid. This Map Adapter is available in raw a finish or black, with mounting bolt.
As always, contact us if you have any questions about this or any of our products.
