Yes this is the much improved K&N filter designed to fit the LT1 5.7 F Bodies.  Much better than Kevin's, but I'll sell for the same price.  $30 + s/h.  I'll even clean it for you so its like new.  No filter tune-up kit included.  Get that at Auto Zone.
I replaced the OE setup w/an SLP Ram Air hood and air box assembly.  This filter works much better than the ram air set-up.  (Not!!!)
IAE, you can easily save about $1400 over the hood mod!!!  See I will save you a bundle.
