Intake Manifold Kit for 6.7L Cummins 2013-2018 Ram - Performance

In this review the Intake Manifold Kit for the 6.7L Cummins is evaluated for Ram 2500/3500 owners who want a straightforward way to free up airflow and improve drivability. The kit is notable for its precision fit to 2013-2018 6.7L Cummins engines and a larger port design that claims an 88% increase in air intake, so the single biggest reason to buy is improved engine breathing and responsiveness without major fabrication. Installation uses factory mounting points and includes the hardware needed to replace the original manifold and grille heater assembly.

Key Features

• Precision fit: Built to match 2013-2018 Ram 6.7L Cummins mounting points so installation is straightforward for those working on compatible trucks.
• Increased airflow: Features a port diameter that is twice OEM size and is designed to increase air intake by 88% for better combustion efficiency.
• Performance boost: Larger intake volume and improved flow aim to deliver quicker throttle response and potential improvements in fuel efficiency under real driving conditions.
• Integrated heating system: The kit replaces the original grille heater with an upgraded plate and vertically mounted coil heater to support reliable cold starts and keep intake efficiency in low temperatures.
• Complete installation kit: Includes washers, gaskets, bolts and special fuel lines so the manifold can be mounted with the factory points without custom modifications.

Who It's For

This intake manifold kit is for Ram 2500 and 3500 owners with the 6.7L Cummins engines from model years 2013 through 2018 who want a bolt-on performance upgrade that focuses on airflow and low-temperature reliability. It suits owners who perform their own mechanical work or who have a trusted shop, since the kit uses factory mounting points and supplies the necessary hardware.

It is not for chassis cab versions and is not intended as a complete engine rebuild component; drivers looking for ECU tuning, forced induction upgrades, or parts for other engines should look elsewhere. Those who need a manifold compatible with other years, models or custom fabrications should verify fitment before purchase.
