K&N air intake install and fuel mileage loss
#12
I have an 05 quad cab. I ran 20 tanks of fuel and hand calculated the MPG for each tank. The overall average was 16.712. I then installed a K&N drop in replacement air filter into the stock air box. I ran 20 more tanks of fuel and hand calculated my MPG to be 16.155. This was not the result I was hoping for...... I am switching back to the stock air filter to see if the MPG will go back up.......

when i got my 2005 dodge diesel truck with 41K miles it had a k&n air filter inside the filter box,
i was concerned about more air flow, then i might get more dirt
so i bought one of the new mopor 4" air filters, i feel better about the air coming into the engine, but my mileage did go down about 1 mpg.
my truck runs like a wild dog and gets great mpg.
you have to have owned an old chevy 3/4 ton to understand where i am coming from.
