Justice Brothers says adding a bottle of its Diesel Fuel Supplement to your fuel tank could improve cold-weather starts, increase horsepower and torque, and reduce smoke emissions. The Diesel Fuel Supplement cleans injectors and the fuel system, lubricates rotary pumps, disperses water, and controls bacteria and algae in the fuel--especially useful for older diesels.

Airaid's new Cool Air Box intake was made for the new Super Duty powerplant. Since the key to quicker throttle response and improved horsepower and torque is airflow, the heart of the system is a huge 1600cfm Airaid Premium SynthaFlow series filter that blocks particulates to two microns. All filters are made with urethane and the system installs in less than an hour. Airaid Filter Company; 888/876-;8984.

Proliance's HBX Heatbuster Extreme high-performance charge air coolers are drop-in replacements for less-efficient factory intercoolers. They feature high-efficiency tubulators and advanced louvered cooling fins to increase an engine's power by lowering the intake charge temperature. Additionally, Proliance's Ultra-Seal grommet technology is designed to withstand punishment and extreme vibrations typically inherent in turbodiesel engines. Proliance; 800/755-2160.

Exhaust brakes are simple: A butterfly valve inside the exhaust stream closes when you lift off the throttle, creating backpressure, which helps slow your engine. But as rpm drops, the exhaust brake becomes less effective. Pacbrake's pressure regulated exhaust brake (PRXB) has a patented wastegate that closes as the engine's rpm begins to drop, maintaining higher backpressure and therefore higher brake horsepower. According to the manufacturer, the PRXB is as effective at 1200 rpm as it is at 2500 rpm. Pacbrake; 800/663-0096.
