Lance,
I also had run a 4" air pipe directly into the stock air box
with a 6" funnel on the end of it on the left side of the
radiator (Cutting the rubber splash boot). Tube was
about 1 foot long straight into the air box. Anyway
I used the G-Tech meter before and after giving the
truck a couple of hours for the computer to adjust
before taking the measurements. The results I got
showed about a 17 HP increase with both the box
mods and the K&N. In hind sight I would of taken
the truck to the strip before and after to see if I
could notice any gain but it's to late iv already
destroyed my air box.
