I took the whole snorkle off of my air filter and run the open element. It works real well has given me a tad more milage ( 20.4 mph on the eway ) and 15.0 with my 28 ft. fifth wheel camper.17-18 around town. Other mods include straight stacks, diablo predator, egr unplug. No leaks .... Plenty of power...... and it will smoke all six.....
