The APR Throttle Body Inlet System is a comprehensive upgrade to the factory charge pipe system from the intercooler outlet to the throttle body. We replace all components and provide a new, larger, free flowing system that flows roughly 34% more than stock! This was achieved by increasing the cross sectional area of the system and by reducing the tight radius bend directly in front of the throttle body.
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.
This comprehensive system is much larger than stock thanks to the sweeping design of the cast inlet pipe, and oversized silicone hose. However, despite being dramatically larger than stock, the complete system is a negligible 2.4 lbs over stock! Simply put, the APR system is a complete upgrade from start to finish, flows better than stock and our competition, and is the only throttle body inlet system you'll ever need!
