Not sure how to connect your boost pipe on your build to the stock OM606 intake manifold? Our billet aluminum adapter bolts right up and allows you to connect a 2.5" silicone coupling with ease, providing a perfect solution for any custom setup. 
 
It comes with two threaded ports for 1/8 NPT fittings to connect a boost gauge, MAP sensor, ALDA, IAT etc., ensuring seamless integration with your build.
 
*Notice that this replaces the stock connector that has the EGR attached, so there will be no EGR with this installed. Please be sure you don't need an EGR and it's allowed by your local laws.
