This is just one step of allowing the 4.7L breath easier.
With headers, ported and polished TB, custom air intake and air filter, the next step is more aggrieve cams.

Below: Intake to the right is the stock 2003 intake. Dodge started using this new design in 2003.
Below: The runners are shorter and more defined allowing better flow and control of the in coming air.
Below: View of the front side from the bottom side.
For whatever its worth, the new one has a different design to it.
Below: The new intake has a larger and smother flow to the casting.
Combined with a polished & ported 68mm TB this new design intake will increase the airflow all RPMs.

Below: Test fitted the stock intake
with layer of insulation. Test to see how the tape would hold
and how it would fit on the 4.7L motor. Test went well. The following
photo are the progression of the work on the 2003 HO INTAKE
By
adding the insulation, the heat off of the top of the engine
block is blocked from being absorbed by the bottom of the intake.
Silver tape will reflect the radiant heat and the insulation
will block the convected heat. This will help with keeping the
intake air cool. I have not done any formal tests to see if this
will make any big difference at all but its worth a try.

foam from a can. |

Below: Painted top with Krylon Fusion
spray paint for Plastic. Cleaned the intake and wiped down with
denatured alcohol. |

Below: Cut back excess foam and started
to apply layer of tape to seal in foam. |

Below: Applied layer of insulation and
sealed with foil tape. |

Below: Bottom view of the HO intake
done, ready and waiting to be reinstalled. |

Below: Installed. Hidden by other ugly
stuff. |

Below: Still hidden by ugly stuff. Watch
for a engine compartment make over. |
Does the it work? was it worth it? Its going to be hard to tell.
But I do know that it's not going to hurt anything.

Would like to thanks Nick at www.airram.com
Nick did this to his 4.7L intake and that's where I got the inspiration to do
the same to my intake manifold. Thanks Nick!!
