Built on a history of integrity, excellent customer service, and innovation, Bully Dog continues to lead the vehicle performance industry with an assortment of great accessories for their intakes, exhauts, and more.
Use the Bully Dog Rapid Flow Cleaner to keep your induction filter clean. Use the oil and pre-filter to keep it that way. Filters must be regularly cleaned and maintained to achieve a lifetime of use. Depending on air quality, filters should be checked and cleaned at least once every three months using the Bully Dog RFI Cleaning Kit, which includes cleaner and oil.
Bully Dog RFI pre-filters are semi-water repellent, will extend the time between cleaning, and will also greatly reduce the amount of time spent cleaning the filter for bugs or other debris.
When added to your diesel fuel, Bully Dog Rapid Power Fuel Reformulator acts as a catalyst by creating a more efficient burn in the piston chamber. A more efficient burn equals more horsepower and torque. Unlike fuel additives, the Fuel Reformulator will also increase fuel economy 3-8% (even in newer vehicles) and can produce significantly higher fuel economy upon first use. Another added benefit? Your engine will be kept free from damaging carbon build-up. One 8 oz bottle will treat up to 320 gallons worth of diesel.
The Bully Dog Pyrometer Probe Kit comes with everything seen here, which includes all the parts and pieces necessary to acquire exhaust gas temperatures to display on the Triple Dog GT, the Watch Dog, or the PMT (PMT comes with all parts seen above). This kit includes one pyrometer probe, which will capture one temperature reading along the exhaust stream. The PCH board, the electronic dock for the pyrometer probe, can accomodate up to two pyrometer probes, offering the ability to capture exhaust gas temperatures for two different locations along the exhaust stream. The Bully Dog devices that utilize this kit all have the programming ability to display up to two pyrometer temperature readings simultaneously. Installing a Pyrometer Probe Kit along with a Triple Dog GT Diesel unlocks the safety defueling feature for defueling based on exhaust gas temperatures.
