My truck is paid for so I guess I can risk a shot of nitrous every once in a while. It won't be any good trying to cruise up a hill but it will sure help on a highway entrance ramp.

I see the NOS-5130 sells for $600. Anyone know where online they are cheaper?

I'd like to try installing it myself. Is there a plate that installs on the intake or does it require drilling and tapping some holes for nozzles? The former is a simple afternoon job, the latter would require pulling the intake and could take a while.
