Shielded spark plug wire Rotax 912

[4Hummer]

Seems my Kitfox 4 that I just purchased came with shielded spark plug wires. The shield grounds to the ignition box behind the firewall ( box houses the coils and mags)

problem is I can’t seem to find shielded wire anywhere. Did Rotax stop requiring this on the 912 ?

heres said box and the spark plug wires (blue). There is a metal retaining bracket that clamps the spark plug wires to the ignition box and affectively Grounds the wires (not showed)

Heres what I did: Ordered standard Rotax Ignition wire and 3/8 shielding, put the shielding over the ignition wire, heat shrink and zip tie near the cap, shielding stops at the ground block that houses the modules.

Ignition box. Tight fit getting all the wires back in there.

There is more blue heat shrink covering the shielding where the wires go threw the firewall (Just as added protection)

Original ignition wires, Badly frayed, and falling apart, pretty sure these are the originals from 20+ years ago

Looks like a good replacement job on some very well used and hard to find original wires. 👍
Your engine has to be pushing 29 years old now considering the design on the ignition system. Not too many sold with the ignition “box” that mounts inside the cockpit but they seemed to be a very reliable design.
Hope she’s running great and flying every day.

This kit fox was purchased in 1992, finished in 1995, only has 157 hours total time, Original builder literally pulled her out of storage from over the winter, did the annual, put her on floats and brought it to the cottage, flew her maybe a couple times a month (Very detailed log books), than back onto wheels and into storage come fall. repeat for 20+ years.

I'm rebuilding/inspecting/replacing parts over the winter, hope to fly come spring.
