Review on High Performance Cold Air Intake Induction Kit with Filter - 4 Inch Intake Pipe - Compatible with 2003-2007 Dodge Ram 2500 3500 5.9L L6 Turbo Diesel (Silver Tube & Black Filter) by Marc Stewart

There are no instructions so you'll have to find out during installation. Putting the parts together in the right order and installing it in my truck was a bit of a hassle. Because of the intake section, the heating grid relay had to be removed and then an engine control light installed. Sounds good with an intake on a truck. You get good turbo whistle from this air intake, although this air intake has quite a bit of heat. Everyone knows that cold air intakes don't actually produce cold air, nobody buys them for that. We want this for sound and more airflow as standard. That's a minus with this inlet, the filter is too small. Brand new, it sucks the air filter sensor red and reduces my truck's performance. This problem was only solved by replacing the filter with a higher quality filter. This kit looks well installed but is inferior to the factory kit.
