The manifold comes with a laser - cut 1/2 - inch thick CNC flange and four 1/8 - inch NPT ports for sensors and injectors. It can work with or without the heater grid. By increasing the tubing circumference to 3.5 inches, it maximizes airflow and boosts performance. The intake and passenger - side cooler tube are made from 3.5 - inch mandrel - bent tubing, with a 1/2 - inch thick flange and 1/4 - inch thick dipstick mounting bracket. Tig - welded components ensure optimal penetration without affecting airflow. You can expect a 50° - 200°F drop in EGTs, a 0.5 - 1 MPG increase, faster turbo spool, and better throttle response. Features include replacing restrictive factory plumbing, a laser - cut flange, multiple NPT ports, grid - heater flexibility, and more. It comes with a 3.5 - inch mega intake system, a 3.5 - inch passenger - side intercooler tube, heavy - duty silicone couplers, stainless T - bolt clamps, an OEM gasket, port plugs, and all required hardware.

Using this intake system is straightforward. First, make sure your vehicle is a 1998.5 - 2002 Dodge Ram with a 5.9L 24V Cummins engine. Gather all the included parts like the intake system, intercooler tube, couplers, clamps, gasket, port plugs, and hardware. Follow the installation instructions carefully. When it comes to the heater grid, you can choose to use it or not according to your needs. As for maintenance, check the connections regularly to make sure everything is tight. Keep an eye on the silicone couplers and replace them if they show signs of wear. Also, clean the intake system periodically to ensure maximum airflow. If you notice any decrease in performance, like a slower turbo spool or reduced throttle response, it might be time to inspect the system for any blockages or damage. And remember, since this is often a special - order product, plan your usage and maintenance around the 2 - 3 - week delivery time if you need a replacement part.
