Not all DOHC cars have low end, but you can change the cam timing to make it have more low end at the cost of top end. AC Delco plugs are all I use and have no issues. Bosch +4s didnt last long in my 3.1, which has the same ignition system. Most people stay away from the platinum plugs that I have talked to or read in discussions over spark plugs.
