Torque Master plugs by TM Engineering. Proven to gain 6whp as per back to back dyno results, search these forums...cl member Meangene did this a while back. I love these plugs and will probably switch back. I just tried Denso Iridium Power and I really feel like it lost power...BUT the idle is MUCH smoother. Pros and cons, pros and cons...
