:just before each throttle body. Not sure what SMC kit is but check out devils-own alcohol injection for any extra parts you may need. I pieced my own setup together from there and it was far cheaper than buying a kit. :You will probably just need a Y fitting and another nozzle (exact same) to make it work. I use my windshield washer tank in the rear to hold the 50/50 mix.
Cool thanks man, It is smc enterprise kit, the guy said to give him $50 for it. I am trying to use a different bottle since I have issues with stock right know
