Like a fire
extinguisher in your house, or an earthquake kit, it’s always better to be
prepared. Although rare, Diesel Engine Runaway is caused when external
hydrocarbons are drawn into the engine and can cause overspeeding and
catastrophic engine failure. Life, limb and your vehicle are put in jeopardy.
BD Diesel Performance has you covered should the worst happen with our
Positive Air Shut-Off (PAS) by cutting the intake air supply to the cylinders
and safely shutting down the engine. The Positive Air Shut-Off butterfly
valve design simplifies the number of parts and reduces the overall size as
compared to competitive units and uses aluminum and stainless components plus
weatherproof electrical connectors to prevent corrosion. Easy installation
with bead boot locks – no need for welding. CAC pipes included for some
vehicles.
