Bully Dog RFI Intake System 53108

Product Description

Fits: 2013-2016 6.6L Duramax

 Bully Dog RFI Intake System 53108 for your 2013-2016 GM 6.6L Duramax LML is designed to outperform your factory air intake system. Bully Dog's Rapid Flow Air Intake System delivers cold, dense air to the vehicle's engine that provides additional horsepower, torque and fuel efficiency. Bully Dog's enclosed intake system keeps hot air out of the intake stream by targeting cold air sources that are specifically designed to optimize airflow. A high flow 8-layer cotton gauze air filter provides maximum filtration to protect your motor without limited airflow. The injection-molded design upgrades the engine bay for a custom finish.

The Bully Dog RFI Intake System features a high quality air filter that is critical to achieving optimal results from an air intake system. All Bully Dog's Rapid Flow CAI systems come with the industry's highest quality filter. Thus, performance is guaranteed. Our Air Filters are manufactured under ISO 5011 specifications to ensure quality. We design our air filters with more surface area than any stock application. Overcompensating for air filter surface area helps guarantee air flow, and will also extend the time needed between necessary filter maintenance.
