oh one more thing...most companies out there have a universal kit which only require you to tap into the intake before the throttle body and those kits can cost anywhere from 5-6 bills. They should include a 10lb. bottle, mounts, relays, steel braided hoses, 2 solenoids (fuel and nitrous), a micro switch that mounts to the throttle body that will only let you spray at WOT, an arming switch, the nozzle and a jet pack that'll let you change your hp shot to whatever you desire.
p.s. mine was a wet system, meaning I also had to tap into the fuel line to couple it with the nitrous right before it went through the nozzle(jet). Therefore wet is safer.
p.s.s. it cost me about $25-$30 to refill the bottle also :licker:
