These are supposed to be some top of the line spark plugs. They claimed about a 5.4 HP gain on a stock VR6. That does seem a bit much, but everyone I know that got these plugs did notice a bit more on the performance side. Every little bit helps, right?!
Yes, of course they don't have anything for the Cougar, but they do have it for the Contour. Two questions:
1. Is the Cougars plug gap the same as the 2.5L Contour? (they show it as 0.054)
2. Is it necessary to upgrade the ignition wires to use these types of plugs?
