I have a 2012 crew cab Sierra and I love it. I installed a KnN intake about 2000 miles ago and here is what I found
Before the intake.
Toronto on New Jersey at night no traffic winter aid temp. 17 to 17.5 mpg at 78 to 81 mph
After
Same trip same time of day same speed.
19.5 to 20.0 mpg. I do this run every / weeks and have run about 4 trips with the KnN.
I also am getting about .5 mpg around the city
Your claim of extracting 15% more NET energy from a gallon of gasoline by changing an airfilter is an outright lie.
Run the truck on a chassis dyno back to back with the two different aircleaner systems then look at the efficiency numbers.
