not sure i know the safe bet on not wasting time is going to coldairinductions. you will be happy with it most of the 3.9 intake systems out there are more of a hot type of intake then a cold one do to allowing heat in to the cone. the heat sheild doesent have the extra heat pad to divert the heat and allow in the cold or cooler air in

 

I looked on coldairinduction.com and i didnt find any actual cold air intakes. The only thing they have up there for the 3.5/3.9 is a high performance air filter. Anyone know where I can find a cold air intake?

 

It's there, you might have to select the 3.9L engine size instead of the 3.5.

2005 - 2009 3.9L Monte Carlo Intake System - 2007 - V-6 3.9L - Monte Carlo - Chevrolet - Cold Air Intakes - Store

 

Nevermind, i didnt notice even if you click on CAI on the top tab, it automatically defaults to Air Filters in the search.
