496 Magnum Flame Arrestor with Vent Tube 

496 Magnum Flame Arrestor with Vent Tube

Both the 8.1 Liter 496 magnum and HP 500 EFI use throttle bodies that are designed to accept clamp-on filters. Although due to size constraints K&N has developed these oval shaped clamp-on flame arrestors to increase the amount of air available for these engines. The shape of this unit allows it to fit under the factory 496 engine cowling.
