Why sparkplug wire keeps popping off spark plug?

Sparkplug wire keeps popping off spark plug ? And i need to push it back into the spark plug, yet both plug and wire are rather new and correct size.

Could it be a loose plug ?

    After market plug wires don't seal properly to the spark plug tower tubes and will cause the plug wire to pop off of the spark plugs

    You could try squeezing the metal piece that snaps onto the tip of the park plug in hopes of it gripping the plug tight enough to keep the rubber seal from popping it off the spark plug.

    If you just bought the plug wires take them back and buy better plug wires.

    You must have a cheap wire that does not fit tightly onto the plug.  It should be hard to push on and therefore hard to come off.

    If it's the type of plug wire that has a hat on the top of it that seals around the valve cover you might have a loose plug that is allowing a little compression to leak past and blow the wire up.

    Put OEM plugs and wires.  That should fix your problem.

    No, sounds more like a damaged wire - they're easy to replace
