Your right i do use it but i have a modded car that needs it so i can hit my 1.6 60ft on a regular basis.......there are plenty of other things that would be much more useful to him if that is really the car he wants to mod.....thats all i was trying to get across.i dont have my srt anymore but it had the one made by MSD. i got no better performance out of it becasue even with suspension the car was a tire frying whore!
