Switch out the restrictive stock heater grid with the open-air Pusher PDC0718HGD Grid Heater Delete. This gives each cylinder a boost with a fully pocketed bottom and an inlet that's 120% bigger than standard. The plenum plate is expertly CNC machined using top-of-the-line 6061-T6 Aluminum and coated in your pick of flashy silver or tough titanium, ready to face the toughest trucking trials.
This product underwent rigorous testing on a SuperFlow SF-750 flow bench and the outcomes were independently verified by Central Florida Machine & Speed. The testing process was conducted consecutively, using the Pusher intake manifold with the factory heater grid attached to the outlet flange as the baseline, resulting in 396 Cubic Feet per Minute (cfm). Afterwards, Central Florida Machine & Speed switched out the factory heater grid with the Pusher Heater Grid Delete and tested at the same inlet pressure, yielding a staggering 528 CFM! That's a remarkable 132 Cubic Feet per Minute increase!
