VMP 1" intercooler line flow-mod kit for 11-17 Coyote
This kit includes the necessary bolt-on manifold bungs, water transfer tubes, and o-rings to upgrade your Roush/VMP lower intake manifold from the factory 3/4" lines up to true 1" NPT fittings.
Our flow-mod kits uses standard NPT threads for easy adaptation to any type of hose. You may use a 90* barb fitting or -16 AN fittings. We recommend 1" ID heater hose for maximum flow.
The stock intercooler system with 3/4" lines and an old-style Bosch pump flows 4.5 GPM, upgraded pumps like the Bosch brushless and Pierburg CW50 will increase flow rates to 6-8 GPM, however, above that, a limit is hit due to the stock fitting sizes. The stock transfer tubes are only 1/2" ID and the manifold bungs only take a 3/4" hose. This will limit flow rates even with larger pumps like the EMP which is capable of 25 GPM with the correct line size.
These fittings in conjunction with a properly built intercooler system can result in temps staying near ambient, or below ambient with an ICE tank, even in the most serious situations.
