I ran a 15.08@93.4mph on my stock OBDII GSR with only intake and exhaust no headers.....then I came back a ran it with ZEX nitrous KIT 75 shot wet clocking 14.22@97.6mph with a 3cylinder running a blown spark plug all day I didn't not know until the next morning when I started up and felt a misfire . I should have bought ZEX Spark plug before I went not the DEALER Laser Platium SPARK PLUG it only for N/A not meant to be use on a Turbo OR a NOS motor. ZEX it safe to use try it out and see it yourself I didn't believe it so I try it myself I beat an TypeR Fully built with Stage 2 JUN cam,JUN valve springs and retainers,Toda Piston and Toda header and Mugen ECU and MUGEN Exhaust ..I could not belived it he spend so much money and I just somke him by like 3 cars hahaha worth my $600 bucks OH remember I was only running with a 3 cylinder and I was clocking 14.5 best after I had my 2nd run with the mustang 5.0 13.56 and 1 run with a Corvette with 14.14. I got smoke .
