I was searching for indexing spark plug articles when I came across this. I know everyone likes their Champs, but I thought some may be interested in the HP increase the Mustang guys showed on their dyno.
"The base pull on our '03 Cobra (with pulley, tune, and exhaust) was 442.98 hp and 466.75 lb-ft of torque. The new Motorcraft plugs gave us an increase of 1.92 hp and 4.28 lb-ft of torque, while the Brisk Premium plugs gave us an additional increase of 5.18 hp and another 0.5 lb-ft. That's a total of 7.10 hp and 4.78 lb-ft for a new best of 450.08 hp and 471.53 lb-ft of torque. Not bad for a simple plug change."

By the way the indexing plug article I found is here. Every little bit helps?
