Well these are a upgrade.
id swap em and throw in new plugs as well as soon as you get em

The regular oems should last for the life of 2 sets of spark plugs. The performance will degrade however after that. My regular oems were still good before i switched to these' so i saved em and put them in genuine VAG boxes that these come in. The 4 regular oems i pulled were at about 20k of usage.
Just be careful when releasing the harness from the head of the coil....now that its getting colder that plastic becomes very flimsy and is easily broken if youre not careful. I would change em when the motor is still warm so you dont pop a clip by mistake.
