You cannot tell from the outside appearance, but this stock looking manifold is milled, filled and ported. So what, you may ask. Porting is easy. For those of you with our Stage I, Stage II or Stage III throttle bodies or our ported Magnum heads, the intake manifold is the next restriction in the system. We modify the intake with porting and extended port matching (not gasket matched....there is a difference). This extended port matching eliminates the bottleneck of the original intake and matches the ports to our Stage I and Stage II Magnum heads. This means the intake can now supply all the air the heads can handle. The milling refers to the port runners being cut to a shorter length. This tunes the intake ram length to a higher RPM. The boost in cylinder filling will move up in the RPM range, which more closely matches the power ranges of performance cams, ported cylinder heads and larger throttle bodies. Filling the plenum area creates a stronger vacuum signal to the fuel injection. This stronger signal helps to offset the signal lost to large duration camshafts and large port throttle bodies. This manifold is the next step in increasing the power potential of the modified engines without having to go to the expense of a 4bbl throttle body system. The intake is supplied with a 1/4" thick aluminum, billet plenum cover plate installed to help prevent blowing the gasket out. Each intake also comes with a new Fel-Pro intake gasket kit and all new torque to yield intake manifold bolts. It's a complete kit! See our Magnum Induction System Modifications for more info on choosing the proper intake.
Customer Testimonial from J.B. in Kelso, WA;
Hughes Engines,
I installed your Stage 1 modified O.E.M. intake on my V6 Magnum along with your Stage 1 billet throttle body and they work great! I am very pleased with the results I got. It runs about 20 degrees cooler and I get about 20 mpg on the highway as opposed to my past of only 16-17 mpg.
Thanks again,
J.B.
