How do I import a spice model into LT spice?
It is possible in LTspice IV to create a new symbol from scratch for a
  third-party model but who has the time? Follow these easy steps to
  generate a new symbol for a third-party model defined in a subcircuit
  (.SUBCKT statement).
  
  
  Open the netlist file that contains the subcircuit definitions in LTspice (File > Open or drag file into LTspice)
  Right-click the line containing the name of the subcircuit, and select Create Symbol:
  Edit the symbol if needed and save.
  
  
  To use the new symbol (and associated third party model) in a
  schematic, select the symbol from the AutoGenerated directory in the
  component library (F2) and place it in your schematic
