i have been looking at MSD wires and ingition coils. do they really help like the site saids or is stock good enough. all i have done to the car is 3.4 pulley, 401 autolight spark plugs, 180 t-stat and U blend delete. not sure if that matters or not

 

Don't bother, they are not as reliable as the stock units and will offer no gains, a coil will only put out the voltage necessary to overcome the resistance of the plug wire, spark plug and the gap and all the connections between the two. The MSD's are pricey too, although they do look good, LOL

un-necessary spending.
