Well...pulled the stock filters tonight along with the carbon filters and installed the K&N's.
This could be due to the stock filters being FILTHY but there is definitely a difference. The truck is snottier and more responsive. There's no doubt about it.
I always thought the truck felt a little choked and i even mentioned to my mechanic at my end of warranty check.
Granted we're not talking a huge difference at all...but the truck definitely woke up from the change. would a change of stock filters have done the same....maybe. But in whatever case i'm very happy.
I took the truck for a spin around the block and all i could think to myself after i let off the gas every time was...."Now the truck feels like it needs a tune..."
The bug.....has bitten.
Someone talk me out of calling Velos tomorrow......
