    I have read about using different plugs for boosted applications. It is time for me to change my plugs however I do not know which plugs will be best for for a boosted setup.
    The car is a 94 cobra 5.0 with stock cam/internals and a full msd ignition. I have read about using colder plugs? what would be the best plug to use and why?

    Does the car still have the stock GT40 heads? (it matters)

    Thanks I appreciate it. Also will the stock gap be okay or should I change it?
