Another Crazy Carls original product!
The Tunnel Ram is a patented intake for the Dodge Cummins diesel engine. It's unique design increases the airflow into the head, which is a known choke point, and distribute the air charge more uniformly between cylinders. Proudly made in the USA of aircraft quality billet aluminum and pressure tested to over 200psi, The Tunnel Ram is able to withstand high boost much better than the stock cast plate. What does that mean to you? Faster spool-up for your turbo, lower EGTs (especially in cylinders 1, 5 & 6 which are prone to run hot) and better MPGs.
The Tunnel Ram was built to be a direct bolt-in replacement for the stock plate and fits with all stock and most aftermarket performance intake/fueling accessories. The compound angles of The Tunnel Ram keep the factory location of the intercooler boot as well. Designed to be used WITH your heater grid or a grid heater delete.
No special tools needed and installation is a breeze, takes less than an hour to install on a cool engine.
Don't suffocate your Cummins any longer, let it breathe with The Tunnel Ram!
Includes full 3pc (upper,lower, and base) gasket kit!
