    You do not need to gap them, just put them in.

    Red D is right, just check to make sure the gap/electrodes aren`t bent or misaligned from being dropped...They come pre=gapped in most cases...PR...

    Well, believe it then....I've never checked a set of Denso's other than visually and never had a problem nor have I ever read or heard of there being one.

    In all reality though, checking the gap is a good practice to get into. Improper gap can lead to intermittant misfires that you may not even be aware of... of course, I think we all know that. Just my $.02

    "Installing new plugs without checking and correcting the gap for your paticular engine application is just a waste of time, effort and money. Gap is important for consistency for the fuel burn in the cylinders. Running too narrow of a gap and the flame kernel will get squashed and doesn't give a good burn. Too wide of a gap causes misfires. The spark may decide to start jumping to the cylinder wall or piston dome, either of which causes hot spots. Hot spots inside the cylinder burn off the incoming fuel charge before the plug fires."
