Our system does away with two potential boost leak points thanks to our single cast design. We've upgraded the factory rubber intercooler outlet hose to a multi-ply wire-reinforced silicone design with strong t-bolt clamps that resist boost leaks better than their stock counterparts. Our new billet throttle body to manifold adapter provides a convenient boost and vacuum reference point which can be used for a gauge, or anything else in that suits your build. Lastly the system comes complete with new throttle body and intake manifold gaskets, which are common problematic leak point many never know to address.
