there r not 4 jets...but yet two jets...one for fuel and one for nitrous....the fuel and nitrous are both plumbed through a shark nozzle which is located in my intake...it is a direct port..i can use this system on the highway it is just limited to 1/4 mi runs because my nitrous would never take remotely close to 13 seconds to release..but that is only if u r runnin a huge shot like 125 n e way
