VMP 1" intercooler line flow-mod kit for 11-17 Coyote

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.
