why spend all kinds of money on an slp lid when you can modify your stock airbox to do the same thing
just unbolt the airbox and put shims under the plastic where it bolts down it will lift your airbox and increase the space where air flows in if you want even more like me trim the plastic lip where the filter sits you will increase the air gap by about 1-2 inches of more air flowjust dont go to high with the shims or your hood wont close
