Connecting spark plug wires to plugs

[MichaelUD]

Old plugs (original 1976 made in Germany) came out easy.
New plugs (made in India) went in easy.
However, I can't get the spark plug boots over the new plugs on all cylinders.
Is there a way to visually see the plugs?
Or do I just keep feeling my way along?
Thanks.

On my BMW I had to unscrew the terminal cap and the wires clipped directly to the threaded terminal underneath. Not sure if the 911 is the same.

I did a "dry run" first.
Pushed the old plug into the new boot to get a feel.
It pushes in nicely.
But I'm exerting a bit of force without success.
I don't like forcing the connection; something else will break.

just keep fiddling, you will know when they are on.

[MichaelUD]

Yup.
I just kept fiddling with it and they finally seated.
Gads! What a process.
Thanks for the morale boost.

I had the same issue. New plugs, new wires. Had to push like hell to get them to seat.

A touch of non conductive lube works wonders...

This. Dielectric grease is your solution. Just a tiny dab.

Mine kind of 'snap' when they fully seat on the plug.

+2 on this.

Just make sure you keep it off the contacts as it is an insulator.

After a few days check them again to be sure they have not popped back off. This can happen if the air inside the rubber end can't escape, if this happens then pressure builds in the boot and as the engine warms this trapped air expands and can cause the boot to pop off. I've had this happen with plug wires that are really air tight where the cable is sealed to the boot with silicone.
