DIRECTION PLUS PROVENT KIT Mitsubishi Challenger 4D56 2011-13, designed to protect its diesel engine by substantially reducing the amount of oil entering the engine from blow-by gas in the crankcase ventilation system.
HOW IT WORKS
Direction-Plus™ ProVent® system separates and redirects oil and air from blow-by gas produced from within the crankcase, which also provides the option of returning the oil back to the sump. By not fitting a Direction-Plus™ ProVent® system in your vehicle it is likely that your engine will experience a progressive reduction in performance.
