Spark Plug Leads DIY
« on: May 25, 2026, 03:23:14 AM »
Hello,

Hopefully someone here can point me in the direction of where to get a small part.. Im working on repositioning the coils so I want to make longer spark plug leads.

I bought a set of spark plug cables NGK from cafe4racer:
https://cafe4racer.eu/en/ignition-cables-bmw-k100-k75-k1-k1100/42924-ngk-spark-plug-cables-sk-for-k75-k100-k100-k1100-black.html

These include the plugs for the bougies but the plugs for the coils have to be re-used.

So Im looking to cut those, and connect them to the new (longer) spark plug cables.

In below Picture I pulled the connector from the original spark plug lead that connects to the coils apart, and it has a rubber sleeve, then the hard plastic 90 degree angled part, and then the wire with the double crimp terminal.

Does anyone know the part number of double crimp terminal as in the picture crimped on the original wire?

BMW doesn't offer them separately in the parts fiches I use. You'd be able to get a suitable one at an auto parts retailer maybe. Suitable ones seem available from many online vendors in the States.
