The 5.4L Triton V-8 pulls air through another Arid-zona company's product. Airaid's intake increases airflow and improves dust filtering, which is all the better to breathe with. The engine cage stabilizes the upper shock mounts and unbolts when needed for better engine access. Behind the engine, the stock automatic transmission was given a cryogenic treatment to strengthen the internals against extended off-road thrashing. A Hughes torque convertor, set up with a 3,000-rpm stall speed, launches the Ford off the line. To keep the tranny's internals alive, hot ATF winds its way through a Fluidyne cooler.
